I never considered a smartwatch but the price on this was so good I decided to try it, with a lot of skepticism. Boy, was I wrong. This is a great watch, the best one I've had even considering those costing five times as much. I've work it swimming, walking, sleeping, received and answered calls on it, gotten texts with it, and it's been absolutely stunning with everything. I'm pretty technical, but I think the setup was very easy, and it's easy to use as well. I seem to use about another 5% per day on battery charge, so keeping it charged isn't an issue; once every ten days or two weeks is plenty. If you get one, pick a watch face that has all your info on it; the face is large enough to hold it. The app is very good; you can see your health stats on it as easily as on the watch, but you may need to sync it (pull down) to get the latest info.
