    • Long battery, lightweight, durable
Color: Black/Midnight Zen
I use my fitbit inspire 3 everyday, mainly to track steps and heart rate. The extra features of Fitbit that require a premium subscription are just OK, and not really needed for me. I did try their free trial, but decided not to continue the premium service. The sleep monitoring is pretty neat though. For connectivity - It is really easy to setup with your phone with their app, but it just isn't for me. The step counter works great, and I use it to try and track my 10,000 steps a day, sometimes finding that I've come close to the goal just doing general work and movement during the day! I like the reminder vibration to remind you to get up and move every once in awhile (I'm sure you can disable this, but I don't). I went with this model of Fitbit because it is much smaller, and much lighter. The fit is really nice, and super lightweight. The screen is still big enough to read it, as the display is bright and clear. It doesn't work well if you want to do extras like messages/email etc, but I don't use it as a smart watch in that way. If you want those features, probably look for a larger model. The durability is another plus for this tracker. I wear it everyday, and without thinking about it (I forget I'm wearing it 99% of the time) I bump and scrape it on all types of things, especially at work because I work with my hands a lot. I can see scruffs and dings all over the edges now after a few months, but zero issues with the functionality, and no real damage to the screen or buttons. Seems that it will take a beating and be just fine. The other thing I really like about this tracker, and another reason I went smaller, is the battery life. I find I have to charge it maybe two or three times a month (at most). I don't really keep track, but it lasts a very long time, even though I wear it all day, everyday. I don't sleep with it anymore, so I'm sure that saves some battery. Either way, the battery lasts a long time, and charge time is very quickly through USB. My only concern is the waterproof type connector that it uses (a design that a lot of smart watches have) might wear down and require their proprietary cable. Because I haven't charged too many times and the charge lasts so long, I'm not super worried about replacing the cable anytime soon, but something to note - you might have to eventually shell out for their special cable. Overall, I really recommend the Inspire 3 is you want a lightweight, small, easy to read tracker. If you are mainly looking for steps/pulse, it is a great device. If you want some of the extras, maybe go a step up and expect to have a heavier device with shorter battery life. ... show more

    • Really like this tracker, but…….see latest update.

I’ve previously had a Charge 4 and then a 5. Like them both, but all good things come to an end. Typical life span a little over 2 years. I’m ok with that. What I really like about this tracker is the smaller size. When my Charge 5 died (tried to wash it off under the faucet), I looked into the Charge 6. Reviews were not reassuring. So this one had more positive reviews and thought I’d give it shot. So far it’s been great. Easy to use, display responds well to touch, screen is legible, and it supports just what I need. Plus, it’s less $$ than the new Charge. At this point very happy with my purchase. Recommended. Will follow up with updates as needed. Update 5-10-24. So within three days battery dropped to 19%. A disappointment given the description states up to 10 days. So I made a few changes in the watch configuration and fully recharged. After36hours battery is at 66%. A week would be acceptable but anything less a disappointment. Update 5-13-24. Turned off always on display. Battery at 44% after 6 days, not bad. Happy I bought this tracker over the Charge 6. Update 6-1-24 Ok, I really like this tracker. Soooo glad I bought it over the Charge 6. It has yet to disappoint me and Im getting at least 8-9 days from a charge. Best part is I like the small profile and simplicity of the display. I see the large display watches and trackers and wonder why anyone would want such a clunky device on their wrist. Now if you wants apps, fancy displays, emergency calling, and all parameters on one screen, this tracker is not for you. So glad I made this purchase. 1-25-25. So the original Fitbit functionality was great throughout the past 9 months until the hinge point of the strap failed. The plastic where the pin secures the strap to the watch fractured. What to do? I tried some epoxy, worked for a few weeks. So I just ordered a new watch. Unfortunately, the watch gave me less than one year of service. Had it not been for its otherwise excellent performance I would have considered abandoning Fitbit. But I went and ordered a new one. Seems the watch is a disposable item with a life expectancy of less than a year. Too bad, seems few things in life have consistent longevity. I’ll have to see how long this one keeps me happy. I’m not going to deduct a star at this point. We’ll just have to see how this goes. 4-11-25 I really like this device. it has performed well. I've been reading a few negative reviews. Seems people expect too much from a small rather inexpensive fitness watch. This device is great as a tracker but is not without fault. Keep that in mind and you won't be disappointed. I think others feel they should get the equivalent of an expensive electrocardiogram or sleep results that you can only get from visiting a sleep center. Ain't gonna happen. Just use the device as it is intended, as a tracker. Overall, once the tracker has accumulated enough data on your habits, it will serve as a reliable reflection of your exercise and health. I think it is worth it and would buy another. 7-10-25 A few more months of use. No complaints. Good tracker. I sync it up with my iPhone and iPad. Sometimes it goes ok other times I need to pair it again. But not a major issue as it does catch up with the latest data. I rely on this compact tracker quite a bit for my steps, distance walked, exercise time, and general sleep quality. it also seems stop on with my resting heart rate. I still like it very much and would buy again. Another update 11-24-25. Watch very reliable thus far. No issues. Again the small profile of this watch is a real plus for me not to mention 8-9 day battery power. Use it mostly to track steps. I have a goal of 11000 steps / day and I’m on track with one month to go for a full year. Will buy another when this fails but I’m hoping to get more than one year out of this one. ... show more

    • Better than an Apple watch, hands down
Color: Black/Midnight Zen
I've been using Fitbit for several years. One time I followed my friend's advice and bought an Apple watch, but was really disappointed in the difference and returned it. For one, Fitbit lasts at least a week on one charge - but with Apple, you have to charge the thing every single day. It also displays far too much useless information - I can use my phone or laptop for that. All I need is the number of steps, heart rate, and sleep time, which Fitbit provides. The only reason I gave this watch a four instead of a five is because it is buggy. The most notable bug is the spotty sleep time. And this is true of all three Fitbits I've had. But I will still give it four stars because I wear it all the time and haven't found anything better, despite its flaws. The fit of this watch is also very good. I have an extremely small wrist, so it's usually difficult for me to find something that doesn't just slip off. But this watch has such a wide range of fit, that I use the fourth-to-smallest notch on the band! ... show more
