I mainly want a fitness tracker to keep up with my steps and my heart rate during exercise. This one does that well. plus some other features such as sleep tracking that many users will like. My previous tracker stopped charging less than a month after I bought it. and I didn't like the charging feature where you had to yank one of the straps off to plug it in. This works with a magnetic charger that attaches to two little dots on the inside of the tracker. The numerals are large enough to read quickly. and the strap has enough holes to adjust the size to a variety of wrists. You download an app on your cell. and syncing is easy -- just make sure the watch is charged and put in near the phone. You can check your exercise data on the watch or on the app. All in all. I think this tracker is a good value for the money.
