  • BEST GET FIT INVESTMENT for those who want to monitor themselves to lose or gain weight
Color: Black Size: Small (Pack of 1)
First time ever to purchase a FitBit of any kind. I decided after researching I wanted a larger screen and switchable straps and easy to use. BEWARE THERE ARE TWO DIFFERENT SIZES STRAP (SMALL WRIST TO LARGE WRIST) I have smaller wrist so I have the smaller size. Doesn't matter which smartphone or PC uses. I used my Android and Laptop to view, adjust and do whatever I want. You can chose which wrist you want it on on the setting. Your Dominant arm I chose the right arm. Some chose the left. I bought a screen protector due to easy to scratch (Illumishield 2ct) (There are much more varieties of screen protectors and lot more than 2 ct go with what customer are saying positive reviews). Once you get it you have to charge it first than first time I use it I had to turn the watch to the bottom of my wrist due to the size of it & can be uncomfortable first time wearer. Only have it to 6 notch on my strap. On my Android I can change whatever I want. I did try to wear it while I slept and it was tight therefore I got a swelling on the bottom of my wrist just because I had it too tight. 6 notch so I took it off a the whole day break from using it and the next day my wrist was back to normal. I now just wear it to 5th notch and I do not care to monitor my sleeping pattern ( If you plan on monitoring your sleep pattern lighten notches from the strap Its pretty cool features tells u how many times I am restless and wakeup ). It is now much more comfortable wearing it on the top of my wrist and no longer get the swelling. So don't freak out that just allergic reaction to having it too tight . Some people have gotten rashes of because of the plastic strap I haven't had that yet because I am not allergic to plastic. They do say to take care of it clean it and give your wrist a break and not wear it all day long also if you feel your not going to be active one day just don't wear it at all (mostly due to bad weather or too sick). There a charger that charge to your Laptop or some sort of plug in you. need to buy separate in order for it to charge. The screen protector that sometime you see when you first get this you don't need to get that one I got one that was low affordable(Illumishield 2ct) had a lot of positive reviews and only two surface protection screen and very easy to put on by watching youtube video. I enjoy the GPS feature in which you can setup walking, Running or hiking and Just click go and the exercise I don't watch it just put it in my pocket and when I come back from my walk I stop it and tells me how long and mapped out where and also maps your pace and how many calories burn it's a cool feature. You can manual put in your walking strides or if you are like me just let the Fitbit Charge 2 do it for you because my walking changes especially if you are in the winter season and the roads/ woods aren't too great. I love the different cardio but I wish they had the Stairmaster selection so I put that under workout because basically it does your heart. I also timed myself at weights and any other cardio workout at the gym it tells me everything from heart rate to how much I burn and so much more. You can chose how many days you want to workout and how many steps and water intake ( water couldn't figure that one out had to check other site to find out how much water I was to take in) and food intake and heart rate, weigh in and how much you want to weigh and so much more. I get plenty of fun badges that tells me I succeeded in making it to 10,000 steps and other successful achievement. They offered Friends challenge and FB other social Platform to show off your success I don't participate that. They offered workout video on your smartphone I have yet to use that feature. There a relax mode you can chose to do 5 or 2 mins breathing inhale and exhale for those who are stress out. Also notification for your texting on your phone. Your fitbit charge 2 will let u see incoming text you can shut it off. Touch screen is very easy to use I watched Youtube and witness a lot of people showing how to use and what you can get out of it. Very interesting and I do not regret my purchase. Another thing on Prime its cheaper than in the local store and if you have Amazon Reward card and rack up a lot of points you can use that and gets lower price than ever. Of course gift-cards you get works too.. I didn't bother with warranty I read other people's comments about it and found the warranty not worth it there already a one year on it and I can just go on to the fitbit site and extend it a little longer. It arrive on time came in a box and protective. I chose black because it matches everything. I can switch it down the road to whatever I want and they offered leather for those who want to take it classier or just causal and many other different colors. This watch isn't water proof but that fine I don't wear watches in the water anyways & protective by my sleeves of my jacket. U can adjust to making u move all the time I don't let it control me yet so I decided when I want to move take it off and I do try to get 10,000 steps ( adjust the steps to less or more) even though it winter time and like 19 or low digit degree out there I just walk inside go to the gym and go up my many different stairs.. Good luck to those who are interested in buying first time wearer or upgrading to something different you will not regret it!! So far I only had it beginning of this year Jan 2nd 2017 and now this is my 9th 2nd week of use. I am so far very happy with the progress. I am still learning everyday about what my fitbit charge 2 can do for me. ... show more

  • Just don't throw it into the fires of Mount Doom- don't think that's covered under the warranty
Ok, so at first I was really, REALLY hesitant about buying the Charge 2 because you never know what problems can arise with new, hot off the press tech. However, I've had wonderful experiences with Fitbit customer service in the past (as in "Hey, my thing stopped working" and they were all like "Sorry about that, here's a new thing- no charge!"), so I feel confident that if anything does go awry, Fitbit will take care of their customers. So, I took the plunge and ordered it. It came today in the mail and I scurried off with it like Gollum and his ring... My precioussssssss! Oh where to begin! Let's see- well it came in lovely, easy to open packaging. Opening up the box felt like I was arousing my Charge 2 from his slumber in his comfy, plastic bed. I immediately noticed that the teal color was more vibrant than its predecessor, and the larger screen gave it an all around sleeker look. The band is now longer, so if the large size from the old Charge was a bit big for you- go for the small with the Charge 2; I have tiny wrists myself, and I'm two notches away from the last ring on the inside! EDIT: I just realized my review was placed under the large size...my Charge 2 is a small. But large or small, only the band is different in length, NOT the screen! The charger was completely redesigned; the days of not having your Charge, well, CHARGE due to it slipping out are dead and gone. The new, blissfully longer charger clips onto the Charge itself, and as long as you align the hole in the charger with the button on the side of the Charge, you're good to go (see picture for reference)! Just make sure you clip it from underneath, and not over the screen or else it won't charge...not that I uh, made a silly mistake like that or anything. *cough* Setup could not have been easier. The entire process from taking it out of the box to having it fully synced and functional was less than ten minutes. Whoa. I was setting it up using the app on my Android phone, and I was expecting that it would need to be charged first but nope! It sprung to life and was ready to go! After it was all synced I checked the battery and saw it was at medium power- right out of the freaking box! Onto features...do you like lots of features? I like lots of features and the Charge 2 has ALL the flipping features you could possibly want. I feel like Fitbit has been personally keeping tabs on me and my current interests. I just recently got into breathing meditation and interval training, and when I heard that the Charge 2 was going to include both these features I was pretty much like, "Shut up and take my money!" After playing with the Charge 2 for about 30 seconds, I came to realize that when you want to choose a feature, for example the breathing exercise, after pushing the button on the side to get to that function, you then hold the button for a second to choose to start it. With the breathing exercise, it allows you to choose between a 2 or 5 minute breathing session. It works by having you breath in rhythm with a ring that expands and contracts on the screen, and it shows your breathing in and out at the bottom with a continuous little graph (see picture to clarify if this sounds wonky to you.) If it comes across as confusing don't worry- Charge 2 guides you through it...it's much more talkative (err, textative?) than the old Charge, and I like it! So for once I was actually excited to hit the hall of pain- uh, I mean the gym, so I could test out my new buddy here. First thing I did was the elliptical; in the past I avoided it because my old charge wouldn't count it as steps. Now all you have to do is select the elliptical option from the workout menu on your charge 2, hold the button on the side and voila! Elliptical steps are now counted! Next I tried out the interval workout option! What's extra awesome about this feature is that it's customizable; the folks of Fitbit really outdid themselves with this one in my opinion. By going onto the app on my phone, I was able to set the intervals to one minute of workout, and two minutes of rest for a total of five sets. Then while I was on the treadmill, I went to the workout menu, chose interval training, and it started right away. Once the minute was up, Charge 2 gave me two little buzzes to let me know to switch to rest mode, and after two minutes gave me another two buzzes to pick it up again. The buzzes aren't very strong, but I still felt them just fine. Then I went onto strength training, and selected weights from the menu (this is all via the charge 2, not the app on the phone). Now the way I strength train is 3 sets of 12 reps, and then a minute of rest in-between. I'm honestly not sure if that minute of rest affects the readings or not, but my guess is no- that Charge 2 calculates everything based on pulse readings. And speaking of pulse readings, it feels like they've improved the technology in that department as well! FYI- I have pretty low blood pressure due to hypothyroidism, so the readings below may seem off, but they're accurate in my case. My resting heart rate is usually between 61 and 66 bpm (beats per minute) So that concluded my gym session. Upon looking at my readings later on, it was kind of neat to compare them. Now the weight training session showed that in 27 minutes I burned 99 calories and had 110 average of bpm. Now with the elliptical, I only did it for 10 minutes, burned 62 calories, and had a 130 average bpm going at a fast pace continuously. With the interval training on the treadmill (here's where it gets interesting folks) for 15 minutes I burned 122 calories with a 148 average bpm. Despite having two minute rest periods several times, I still burned more calories and had a higher heart rate than the continuous workout on the elliptical. Interval training all the way! Although...I wonder if you could do interval training on the elliptical and still have the steps count. I'll have to experiment with that... *EDIT* Yes you can in fact do interval training on the eliptical and have steps count! There's still so much to try! The connected GPS looks like a pretty neat feature, and it's a nice extra to include! I'm not much of a runner myself being bite sized, but you can still track location for other things like walking, biking and hiking. Then there's call, text, and calendar notifications (adding the calendar was a great idea). You can also change bands now, so if you wear out your current band (like I did with my old Charge- bubbling issues anyone?) or just want a different look, you can switch them whenever your little heart so desires. Oh! And there's lots of screen options that you can choose from like a dial watch, extra bold print, and having time/date/steps/heart rate all together (which is what I ended up choosing)- and that's just to name a few! *EDIT* So they added a feature which shows your fitness level by going into the heart rate section of the app and then swiping left to get to that screen. I originally thought it was fitness test type thing, but I misunderstood. The app already calculates your fitness level for you based on several factors (resting heart rate, your bpm during exercises, and other information collected from your profile). So sorry for any confusion! No tests for you. Alas, there is but one problem I have encountered so far. I was walking while holding my phone in the hand that my charge 2 was on, and noticed that it didn't count my steps. So after experimenting for a bit (holding up my hands like I was pushing an invisible grocery cart, though it probably looked more like I was pretending to be A zombie) I came to the conclusion that if your hand is held up flat (palm up or palm down) in midair, like when holding a phone...the charge 2 doesn't register steps. However, it should be noted that when I put the charge 2 in workout mode, it DID count some of the steps, even when holding my phone, but it didn't seem to accurately count them all. I guess the solution is don't play on your phone while you walk? Or at least leave the hand with the Charge 2 on it by your side when playing Pokemon Go- you can play with one hand, right? Everything considered, this is truly an amazing piece of technology that is priced extremely fairly for all that it offers, including the best fitness app that is included at no extra charge. Thanks good guy Fitbit! In conclusion... This is the one fitness tracker...TO RULE THEM ALL! UPDATE: 9/20 Yes yes, I know what you're all thinking- how could I possibly make this exceedingly long review even better? MAKE IT LONGER! Battery lasted from Wednesday afternoon (after fully charging it) to Monday night. It should be called Fitbit doesn't need to Charge all that often, amiright? Eh? Motivation Man! Every hour (just day hours, or you can customize which hours and days you want in the app) you don't move (or hardly move), Charge 2 gives you a friendly little buzz, and the animated little Motivation Man (as I like to call him) says something cute on the screen like "Take me for a stroll?" or "97 more steps!" (to reach 250). Do it. Don't let Motivation Man down. With the Fitness level tracker, my original score was placed in the good category and I was all happy that I was fitter than I thought. Well, the app suggests that if you want a more accurate reading, that you should go for a ten minute run outside with your Charge 2 synced to your phone for GPS tracking. So although I hate running more than kids who kick your seat continuously on a long flight, I did it. Upon looking at my fitness level thinking that my score was going to shoot up, it dropped down to fair, which is right after poor. Ouch. I mean in all fairness it's accurate but still...ouch. Went from feeling fitter to bitter. What's not accurate, however, is if you're at the gym and your Charge 2 syncs with your phone app for gps tracking. A few times while I was on the treadmill or elliptical, the GPS kicked in and gave me crazy readings. Now don' get me wrong- my step count wasn't affected in any way, the app just showed me a map of the wacky, non-existent trail that went though multiple buildings and over a river. You can just delete it of course, orrrrrr you could show it off to your friends and make stuff up...like I always teleport over rivers when I work out, doesn't everyone? The Fitbit app added a seriously impressive fitness game called Adventure challenge (it's in the challenges section) where your step count is shown on an actual map, like Yosemite Vernal falls to start off with, and the more you walk, the more you travel along the trail. Along the way you come across markers, and when you reach them, it shows you where you are on the trail with gorgeous panoramic pictures (hold up your phone, slowly turn left and right, and the picture pans out either way). There are also random "gems" on the map, and when you click them they either have a fun fact, a health multiple choice quiz, or a health challenge (like do tricep dips on a chair for a minute). You can collect them and earn a badge...or not-completely optional. However, I personally am having a blast with it, and I'm sort of stunned that they're including it in the app for free! It's like having an expensive dinner with Fitbit and when the check comes, Fitbit is all like, "Hey, it's cool. I got this,"...you sure do Fitbit. You sure do. ... show more

  • Charge 2 good device. Fitbit poor customer service; poor response to tech issues.
Color: Black Size: Large (Pack of 1)
Charge 2 tracker is a great tool when it works as advertised. I caution all who purchase to have an expectation that you will experience frustration with the tracker due to ongoing, reported software bugs. I also recommend that you use your search engine to get an idea of the problems you may experience. And finally, have NO expectation that Fitbit will provide any assistance with problems. Received my Fitbit as ordered. No problems there. I love the product WHEN IT WORKS as advertised and intended. Unfortunately, problems begin once you start using the Fitbit. There are technical issues that remain unresolved for months after being reported. Syncing issues are abundant - frequently your tracker will not sync with the Fitbit app on your connected device and this is rarely resolved easily. Note that using all day sync (recommended setting) can interfere with other Bluetooth devices you might wish to use with your phone/tablet/computer/whatever. There are issues where the tracker does not reset correctly at midnight - clearing your counts/measurements from one day to the next. There are issues where the tracker does not count all steps while you are walking or exercising. This is a separate and distinct issue from the lag the tracker experiences when you are still and start walking which is not an issue. It is frustrating because your expectation is that this device is "ready for prime time" but it is not. Frankly, I feel that the software loaded on these devices is continuously in Beta test mode. Which would be fine if you purchase the device with that understanding. Fitbit responses from Customer Service simply say "their engineering team is working on it". They are unable to provide any time frame for resolution of any issues. Their customer service is at best handled by folks whose native language is not English and at worst, robots who simply provide canned answers. I have tried communicating with Fitbit Customer Service via online chat, their user forums, and email. At no time did it seem as if the person (or whatever) on the other end even paid attention to what I had reported. They repeatedly referred me to broken or closed links in the online community forum. It is disturbing that they can offer no help thru any of the resources that was not from their community boards. Are there no customer service people with technological knowledge that goes beyond what the user community has found by trial and error? No. The stock solution is to basically turn it off and turn it back on. Conclusion (repeated from opening): Charge 2 tracker is a great tool when it works as advertised. I caution all who purchase to have an expectation that you will experience frustration with the tracker due to ongoing, reported software bugs. I also recommend that you use your search engine to get an idea of the problems you may experience.

  • Charge 2 is the best version of fitbit I've had...
Color: Black Size: Large (Pack of 1)
I've had a long history with Fitbit. I think it started around 2012 or 2013. I've been them a while. And a lot of it hasn't been that pleasant. It all began with the Fitbit Flex. Luckily I took out a extended warranty on it when I purchased it through Amazon because it suddenly died when it was just over a year old. In addition, even before that flex died, I had problems. They touted back then that you could shower with the Flex yet the band disintegrated after a few months. My extended warranty hadn't kicked in yet and fitbit's customer service wasn't exactly that friendly about it. I had to jump through a lot of hoops to get them to replace that band. Then, when the Fkex completely died, I was able to get a new flex. I figured that it would last a while especially if I didn't get it near any water . But it was just under a year old when it died. I never showered with it or got it around water either. It just didn't hold up. Then, after that I bought the Charge HR. It didn't have a removable band and once again the band begin to disintegrate and it was only around 6 months old when that started happening. I tried to put it back together with Gorilla Glue and it looked so tacky that I was ashamed to wear it - especially at work. Why do have I stayed with Fitbit so long? I'm not really sure. I know that there are a lot of great trackers out there now but I guess because Fitbit was the first tracker I've owned and loved, I stayed with them. They were among the first to introduce technology that really motivated you to get up and move. Whole social networking Community spring up around the Fitbit. And for me personally, it motivated me for the first time in years! When I first got it I was quite overweight and I began getting 10000 plus steps everyday. Even on days when I worked late and I wasn't able to hit the walking trail or the treadmill, if I was close to that step goal I would jog around in my house and go up and down my stairs to hit that goal! I was so stoked when that buzzer would go off on my wrist indicating that I had reached my step goal for the day! And even motivated me to stop looking for the closest parking spot at the grocery store just so that I could get in more steps! It definitely wasn't your mother's old fashioned pedometer. Also, I've been with them since 2012/2013 and I have a history on their app of Lifetime miles and I didn't want to lose that. I guess it's just blind loyalty. That's not my typical style and for all that I've been through with them, it's kind of undeserved. But fast forward to today and I'm kind of glad that I hung in there with them. I love the Charge 2! I love the replaceable bands. I love that you can buy quality bands at a reasonable price that look like jewelry without having to go through the Fitbit company. (Remember back when the Fitbit Flex was new and you could only buy replacement bands from Fitbit that were ridiculously priced and in order to get the basic black, you always had to buy some extra colors that you didn't want in a 3-pack because the price of the black band alone was almost as much as the three pack. Then, other companies started making them and selling them on Amazon in all kinds of cool colors and designs at cheap prices. Unfortunately, as soon as I bought a whole slew of them, the second Fitbit Flex died and I was stuck with them.) I love the new charger style as well. With the Charge hr, sometimes the Fitbit would just fall right off of the charger. I would put it on to charge overnight and wake up thinking my Fitbit was charged and ready to go only to find out that it was dead. With this little clamp, it stays right in place. I love the extended battery life that the Charge 2 has and all of the reminders about getting up to walk. I'm really enjoying it and I'm hoping and praying that this investment holds up. I hope it lasts longer than a year. If it doesn't I will update my review!) So far, I think this is the best version yet! ... show more

  • Absolutely in Love!
Color: Black Size: Small (Pack of 1)
I am totally obsessed with my Charge 2. I had the Charge HR about a year ago, but I had to return it after my wrist broke out with a terrible rash (and yes, I was taking care of the band properly). This time, I didn't wait to have problems. The Charge 2 allows you to switch out bands! This seemingly superficial feature was critical for someone with sensitive skin, like myself. I use a stainless steel milanese band for everyday use and a cheap silicone band when I'm working out. I find it pretty easy to switch out bands, and, best of all, NO RASHES! Onto the features that others are probably more interested in... - Steps: Seems accurate. Doesn't pick up "false steps" from wrist movement, such as typing. - Heart rate: Seems accurate most of the time (consistent with iPhone heart rate app, blood pressure monitor, and oximeter). - Floors climbed: Questionable accuracy? Seems to add extra floors in during my day. - Sleep tracking: Seems accurate. - Exercise: I love that it's able to sense if I'm on a run or walking (haven't yet used it for other exercise, such as biking). It's nice not to input this separately! - Hourly Activity: Probably one of my favorite new features. You can set your 9-hour time range (default 9-5) and it encourages you to take at least 250 steps during each hour. If you haven't hit 250 steps 10 minutes before the new hour, it reminds you to move. A great way to remind yourself to move a little each hour! - Notifications: Another great new feature! If you allow bluetooth on your phone, your Fitbit will vibrate when you receive a call or text. It will display who is calling or texting, and, in the case of a text, will stream part of the text across your Fitbit. Wonderful for someone who has their phone on silent during the work day. - Silent alarms: Works fine - Stopwatch: Works fine - Relax: An interesting feature that helps you do slow breathing. Intervals of 2 mins or 5 mins makes it easy to use as quick "relax breaks" throughout the day. - GPS: I don't use this, but it can help track your runs and give you a more accurate cardio fitness level. The app: IS GREAT. I love how easy it is to navigate the Fitbit app, and all the great graphs it provides to help you keep track of your data. It automatically keeps track of steps, miles, floors, calories out, "active minutes" (periods of moderate activity done for 10 minutes or more), days of weekly exercise, sleep, hourly activity, and heart rate. You can also input data to keep track of weight loss, water intake, and calories in (food journal). If you already use a program like MyFitnessPal, it can sync the information over so that you don't have to input it twice. Unfortunately, the information can't sync to Apple's HealthKit without a third party app. FitSync is a great one that will help transfer data to HealthKit. For those in Weight Watchers, the activity will sync to the WW app as "activity points"; however, the food that you input into the WW app will not transfer over to FitBit. Battery: Certain features may drain your battery quicker, such as silent alarms and notifications. My guess is that without these features, the battery life is probably 5 days. I get about 3 days from it. It's easy to charge, and doesn't take much time to charge up. Since it shouldn't be worn in the shower, I normally just charge up every few days while I shower. That way, I never worry about the battery, and I'm not missing steps when it's charging! ... show more

  • Performs as expected
3/31/19 I have had this thing less than a week so I am still on my honeymoon. Here are my first impressions: It appears to work as intended. If one wants to just scamper around the neighbourhood it is perfect. It dutifully counts “every breath you take / every move you make / every bond you break / every step you take”. The heart rate reading matches that of other gadgets I own. I noticed right away that it seems to count not steps but arm movements and converts these into steps by means of a complicated algorithm. First, I spent two days spreading mulch from my truck and hit 14,000 steps each day! Well, it counted each forkful as four steps: into the mulch, out of the mulch, into the barrow, put the fork down. Actually pushing the wheelbarrow to and from the site counted as zero, no matter how far I travelled, as my arms were not swinging. Then a few more ‘step counts’ to unload the wheelbarrow and spread the mulch. The next day I went to the gym (as if my poor old body hadn’t suffered enough). Here I realized that ten “flights” on the stair machine counted for zero as my arms were not swinging and my altitude did not change. I guess the rowing machine and the elliptical trainer will add ‘steps’, but the treadmill and the stationary bike will not. I scored more steps loading and unloading the weights on the barbells than I did actually doing squats or bench presses. A wee bit of research on the interwebs showed me that remarkably few calories are expended in weight training. Something to do with kilograms and meters and joules, oh my. The free Android app gives me some cool charts and graphs but seems to have no way of entering all this sterling work into my daily totals other than just calories. It displays my VO2 score (shampoo?) and tells me I am in pretty good shape for an old man. The free Fitbit Coach app seems stuck in the isometric era and similarly does not enable input of weight training results. It nagged me to enter food intake but provided no way to convert cookies to calories, in a manner of speaking. I checked the Amazon reviews and found that the third-party app MyFitnessPal linked to Fitbit and facilitated the entry of food calories. • I like the way the Fitbit tells me the time when I look at it although I sometimes have to whack it a couple of times to get its attention. • It is cool-looking on my wrist. • I can set my pace length or let it detect it automatically. • The stopwatch function works well and is easier to use than the app in my smart phone. • The sleep monitor also works as expected; giving me information I already knew and didn’t really care about. It could be handy if one has sleep problems • I have not tried all the notification features, such as email, and probably won’t. • Neither have I tried scampering around the neighbourhood as that is not a part of my exercise regimen – yet. • It connects seamlessly with its own Android phone app and the MyFitnessPal app. I purchased the Charge 2 Fitbit as some Amazon reviewers said it was better than the Charge 3. I also bought the three year protection plan, something I rarely do, as reviewers said the device sometimes fails after sixteen months. We shall wait and see how this pans out. I give it five stars because of the reasonable price and that it performs as expected. Time will tell of its reliability. ... show more

  • So many improvements over the Charge HR, but still issues with longevity
Let me start by saying that I purchased the Charge HR a little over a year and a half ago and experienced so many issues. My Charge HR died two times over the course of 6 months. Everyone I knew who owned one experienced similar issues. Fitbit customer service was always really helpful and would replace the faulty products without question (as long as you performed some troubleshooting first), but you were still left a week or two at a time without the product while it was being replaced. That being said, I was very skeptical about purchasing the Charge 2 when it was released. After my Charge HR died for the third time and after reading initial reviews on the Charge 2, I went ahead and purchased the item to give it a try. I am so happy that I did. The Charge 2 contains so many improvements as compared to the Charge HR, and I feel that many were made specifically to address those issues. First off, they made the band replaceable. This fixed all the issues with band durability (the Charge HR had many) as the bands are fairly inexpensive to replace. It is also just a nice feature to be able to change your band around. Second, and I feel most importantly, they made the charging cord something that you fasten to the core of the device rather than have to plug the charging cord into a hole on the back of the device. Not having the hole in the back for the charging cord connection (as on the Charge HR), has saved me so many problems. I am very active, so I sweat a lot and get dirty a lot, which I believe is what caused many of the problems with the prior iteration of this product. I no longer have issues with my salty sweat, dirt, or sand getting into the hole on the back of the device and creating electrical problems. I have had my Charge 2 for a little over 6 months now with no issues regarding how the device performs. Also, as a plus, the software that works with the Charge 2 contains many upgrades. There is more detail in the tracking that the device performs and your screen display is customizable. On a side note, some folks have complained about wrist pain from using this device. I did experience this after the first few weeks of wearing the item. The pain felt like a combination of tendinitis in the elbow and arthritis in the wrist. I thought I had hurt myself playing sports, but realized when I forgot to wear my Fitbit for a day, that the pain went away. Needless to say, this concerned me. I tried wearing the band looser, not sleeping in it, but none of this helped. What solved the problem was when I ordered an additional band from a manufacturer other than Fitbit. When I put the new band on, I realized that the curvature around my wrist was a little wider. This alone seemed to fix all of the issues that I was having with the pain in my arm. It should be said that in my experience when compared to a chest strap monitor, the tighter curvature of the actual Fitbit product seemed to provide more accurate data. However, the wider curvature of the off-brand band relieved all of my wrist pain issues. The difference in stat tracking was, in my experience, very slight, so I have opted to simply buy off brand bands to avoid the wrist pain. I've experienced no more pain and have been very happy with the product ever since. Also, the manufacturer may have addressed this issue by now, but this is based on my experience from when I first purchased this item around 6 months ago. All in all, I would highly recommend this product. Update after 2 years of ownership: The fitness band stopped tracking my heart rate after two years. None of the troubleshooting steps worked, so I've had to order a new one. It seems that this is a common issue among the Charge 2's. At around 2 years either the battery starts losing its ability to hold charge or it stops tracking heart rate. Unfortunately it appears that there aren't really any consistently good fitness trackers in the under $200 category, so it is a matter of picking your poison. I'm staying with Fitbit because my community of friends are all on the software, but I long for a day when a durable and affordable fitness tracker is on the market. ... show more

  • Interesting device for the price
Color: Black Size: Large (Pack of 1)
Been using this Fitbit for a couple weeks now, and so far so good. Overall, I impressed by the build quality, and its functionality. I will not attest to the device’s accuracy, but it doesn’t seem like it way off its mark. If anything, I would say that it might be measuring slightly less than what I’ve actually done, and I’m perfectly find with what. That just means I have to work extra hard to meet what ever quota I set for myself, and if the means I have to do an extra 2-5% more due to the low count, then so be it. As for the other functionalities, heart monitors seem to be accurate to with a heartbeat or so. I’ve used two other methods to measure my heart rate, and compared those numbers with that the Fitbit was reporting, and they were all within a beat or two of each other. That either means the Fitbit was dead on, and the other two devices I used was off, or the other way. Either way, I would say it accurate enough for a layman user like myself. Battery life was OK when I had continuous monitoring on; I would get about 2 days on a full charge. By the end of the second week, I realized I didn’t really need it set to that and switched to manual check-in, which I do at least twice-a-day. Doing these increased the battery life to 7 days, with the battery consistently reporting about 35% charge left by the end of the 7th day. At which point, I take off the Fitbit and charge it before bedtime. I can probably get another day out of it, but since I got Sunday to Sunday on a single charge, I don’t want it to die on me sometime during the workday on Monday. The sleep tracking feature is quite neat, curious to know how they base the accuracy of when a person is in Deep, Light, or REM sleep. I do have two issues with Charge 2 Fitbit. The first is the charging clip. On more than one occasion, I’ve thought I connected the fit correctly to the charger, paying attention solely to the vibration it gives out when its connected, and not the screen to see if the battery symbol pops up. Relying solely on the vibration, has resulted on me coming back to a nearly discharged device. Not sure when the Fitbit vibrates when the clipped to the charger, but not actually charging. It’s a weird “feature”, and one of which I would have done without. The second issue I had, and immediately rectified was the stiff wristband it came with. That thing was so uncomfortable, that I thought I had made a huge mistake in purchasing the Fitbit. After a couple hours with it on, I want to rip that device off my wrist. I mentioned this to my wife, and she suggested I change out the band. It’s didn’t even cross my mind that I could do that, I feel silly now that I didn’t think of it myself, but I did just that. I purchase the nylon Fintie Band [https://www.amazon.com/gp/product/B07GX9CZFV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1] from here and it made a huge difference in the Fitbit’s wear-ability. I do have to give Fitbit kudos for designing such a simple mechanism to swap out bands. ... show more
