I love the look of this hybrid watch! It was exactly what I was looking for, the look of a traditional watch (a watch face with hands) and also a fitness tracker. I wish the battery lasted longer and I am still trying to understand all the watch's features but I am very happy that I bought it.General information , difficult to access on line as Garmin site is often busy ….. easy to use , but took over 45 minutes to get on line ..I was really hoping that this would live up to my expectations, but it is a big disappointment. It’s great for tracking workouts, but that’s about it. I just wanted something simple for my workouts and sleep, but this thing drops the ball big time with sleep. I know that no sleep tracker is 100% accurate, but it will say I almost slept like a baby when I was up five times, or will count everything in the wrong category (wake ups in deep sleep, for example- which are not even close in their HR ranges). I don’t even use it for sleep tracking anymore; it’s just an expensive workout tracker for me now. Really wish I hadn’t purchased.It seems to work well but the battery life is only 3 or 4 days if you wear it at night. Amazon suggests that you buy a face protector with it. I did but the face is slightly domed so the protector doesn't lie flat and collects dust around the rim. If you don't use a protector the face gets scratched up easily.
