    • Solid android-compatible smart watch
Color: Pink Gold Size: 40mm Style: Bluetooth
I decided to upgrade from a fitness band/watch garmin device to this smart watch. I know there are about 3 subsequent versions of this, but mine still works very well after over 2 years. Positives: - I like being able to see at least part of incoming text messages so I can decide if I need to pull out my phone to read them on a larger screen. - The do-not-disturb feature is very helpful in muting text messages when I can't afford interruptions - I do like the variety of fitness tracking options, as well as health and sleep - The battery life is still pretty good even after several years Negatives/downsides: - I still find it hard to cancel notifications rather than just snooze them (the swipe to clear feature doesn't always work--could be the screen protector I use) - It took me a while to realize that having the watch on DND means that calls won't go through on my phone even if the volume is on for that device - Battery does have to be charged each night, which limits the usability for sleep tracking (unless I charge it earlier and then can't track activity/steps) Overall still a quality device and I haven't been compelled to upgrade yet. ... show more

    • Great value
Color: Pink Gold Size: 40mm Style: Bluetooth
Love the color. Bams is perfect, even for my very small wrists. Connects to my phone with no issues. I do wish the battery lasted a little longer. Seems to track activity accurately.

    • Great Watch - Not Perfect
This is my 3rd "Smart Watch". My 1st was a Garmin which was very basic and bought by my wife. I was an avid runner and that was the Garmin's main intended purpose. However, shortly after receiving it, I had to give up running due to prolonged issues with my hip. So, it became a very expensive heart rate monitor - a function at which it excelled. My 2nd watch was a Fossil watch which was an impulse buy. It was visually attractive but excelled at nothing else. It sits on my bedside table and is rarely worn - poor integration with my phone and poor battery life make it slightly better than useless. [A cautionary tale against impulse buying.] I have been hesitant to pull the trigger on a more expensive smart watch but I lost the Garmin watch and really missed having a continuous HR monitor when I exercised. I am an old dude but my fitness is very important and HR zone targets have a proven benefit. It also keeps me on track in the gym. Well, I saw the "renewed" version of this watch, and the price point made it an almost painless proposition to give it a try. So far I love it. I have a collection of watches and usually rotate them for work but since buying this watch all of my other watches are collecting dust. The setup was painless. I have begun using an exercise app that has a continuous HR monitor and workout timer. This is the feature that is most important to me but I love playing with the other features. I emphasize "playing" because none of the other features are terribly important to me - they are merely novelties. But over time I feel some of the features will become second nature. I love being able to see my messages on the watch while at work but with Android I can just as easily see my messages on my laptop while at work [can't do that with Apple!]. Overall, a solid watch. MAJOR CON: battery life. Given the small footprint of this watch, and all that it is doing in the background, I feel a bit like an entitled brat complaining about the battery life but, if I could change one thing, that would definitely be it. ... show more

So I had the very first version and while it was cool, it was limited as far as the fluidity between watch and phone. But that's not the problem here. I'm a geek/nerd not a doctor so I'm not tryin to sell anyone on the health features on the watch but from a geeks point of view, it's a cool lil doohikie to play with. Sleep tracker, body composition recorder I guess (very cool), blood oxygen level reader and a plethora of other geek features are in the mix for you to ooohhhh and aaaahhhh over as I did. There's an app to download in order to sync faces and your phone with the watch but the app isn't something that's used regularly unless your directly messing with the watch like changing faces or things like that. Speaking of such, you can personalize the faces. Even import your personal pics to be a face on the watch so that's cool. My only issue is the battery life. I'm a geek so I've got a lot goin on in my phone so I understand that its a pretty heavy battery drain. The same seems to be said for the watch. But like I said, the activity and connections that's I have goin on between phone and watch is why it drains so quickly so that's something to take into account. But if there aren't multiple apps connected and the ECG reader aren't active, the watch lasts for quite a while. Some 30+ hours. Texting on it can be a bit of a hassle but c'mon, your phone is right there. The option is just for quick yes, no, be right there kinda answers. Not carrying full convos. The feature to answer calls (if you have the Bluetooth edition) is smooth and very easy to use. Overall, no real problems and satisfaction definitely achieved on my end! Happy customer here. Update: so cancel what I said previously about not really being able to text. An update was added and you can text and send emojis easier than imagined! Close to a complete device! ... show more
