This is a bit lengthy. I wanted to cover everything... I researched this watch vs. the Moto 360 2nd Gen and decided to go with the Huawei due to the full-screen AMOLED display and the removable back in case of future battery replacement option. Also, it reportedly has a speaker for future updates to Android Wear. I was hesitant to buy a smartwatch and worried I'd regret it. Since I was watch shopping anyway, I am happy I spent the extra money for this watch and don't regret the purchase at all. It's nice seeing who's calling, texts and emails when you don't want to grab the phone from your pocket, console or drawer. Changing faces to suit the mood or occasion is also a nice feature. I totally love it and hope updates bring even more functionality. I am very happy with it after a week of use. It's very nice looking, great display, not too large, and provides the functionality I expected from a current smartwatch. I have had no problems with connectivity to my HTC Desire phone. Never randomly disconnects and doesn't disconnect easily or quickly when leaving the phone area. In fact, it's only disconnected when I was intentionally leaving the area, and reconnects promptly when returning. The Huawei tracker seems very high in step count, but surely shows a good picture of a day's physical movement comparing one day to the next. More like an activity score for the day. I hope that future updates will improve the accuracy or allow for sensitivity adjustment. It also offers a handy single activity tracker in addition to the always on daily tracking. Google Fit seems a little more accurate when it's tracking, but it is harder to understand what and when it's tracking on the watch and/or phone. I'm still figuring that out. I have only used the heart rate monitor while my wrist is still, and in that case it seems very accurate with my complexion. I've downloaded a few apps and lots of faces and most seem to work well. I don't use always on (Ambient Mode) or the wrist turn detection, just tap to see time and functions when I need them. I turn off the watch while sleeping when it's not charging (approx. every other day). The battery life is great in that case. High use in the first couple days, but lower now that "normal" use is settling in. Perhaps I'll get three days on this latest charge.
