For the battery complainers
Yes, battery consumption is not good. With BT on (AOD off) the watch was using about 15-20% just sitting idle overnight. Not good. I turned off BT overnite and it used 4% in about 8 hrs, much more in line with what it should be. If you can turn off BT periodically you will see a big battery improvement. It's not a perfect solution but these devices are still in developmental infancy. With it's faults it's still a technological marvel. As a kid I recall seeing Dick Tracy talking into his 2-way wrist radio wondering when we would have that. About 70 years give or take. ... show more

I love this watch!!!
I have wanted this specific watch for a very long time now, so when I found this incredible deal here at Amazon, I simply could not pass it by. I have always been an iOS user, but I prefer the Samsung Galaxy watch to the Apple watch hands down. I love the rotating bezel and hope Samsung will return to it in their future editions. The shipping was very fast, the watch works perfectly and I could not possibly be more pleased. For these reasons and more, I would highly recommend this watch and this seller to others. This watch is indeed the perfect birthday gift for me and would be the perfect gift for any occasion IMHO! ... show more

I love this watch! However,...
This watch is awesome. However, the battery life only lasts from 7:00 a.m. to midnight. It's a little on the heavier side. The sleep tracker I can't open all my phone still. The only information it will give me as of now is how many hours I have slept. There aren't a whole lot of options for watch faces and I don't really trust a third party app for that. Other than that, it's exactly like an Apple watch. ... show more

Easy set up
Beautiful watch and set up was fairly easy for a tech challenged person like myself. The band is much softer than expected and I was pleasantly surprised. Really sleek and clean style. I feel so much safer with the SOS fall app!

Did not think I would go back to wearing a wrist watch
I did not think I would return to wearing a wrist watch but this watch can do everything my phone can. I am no longer slaved to my phone. I can answer calls, reply to texts, listen to music, check on my health - I can do so much more than just look at the time.

Disappointing
I have so many Samsung devices, that when my fourth fitness tracker from another company died I decided to give Samsung a try. Here are the pros and cons. Pros: ============== -The Samsung name. -It has many more features that I will every use. -The design feels sturdy and I expect it to be durable. -It is attractive enough for a smart watch. Cons: ============== -The battery life sucks. Even in battery saving mode, the watch gives you a maximum of a day and a half of charge. Mind you, I don't really do anything other than look at the clock, my heart rate, and steps. I do not answer the phone with it, or send messages, etc. My old fitness tracker, which granted had fewer features, would last upward of a week doing the same thing. -Sleep tracking is a joke, because again the battery sucks. -You cannot remove unused apps from the watch. Electronics manufactures love to load smart watches, phones, PCs with stuff you don't need and will never use. Considering these things often work in the background and use energy, it would make sense to be able to remove them. -It is incredibly thick. -There is no way to know by the packaging whether you are getting a US or international version. Found that out the hard way with the first one of these I bought. Try registering an international version in the US and you will see why this is an issue... though I would argue there should only be one global version for something like this anyway. There is no reason why the end-user could not just install the region specific software they need. -The US version has a shorter warranty (1 year) than if you live in the EU (2 years). Hey, either your device will last two years or it won't. Give us the same guarantee you give others. Given the issues I have had with Samsung products over the years; washers that throw baskets through walls, Note phablets that catch fire, and a monitor that started black screening about a month after the warranty expired... I guess shame on me. ... show more
