    most functions of the watch don't work
  

*by M***S on Reviewed in the United States on September 17, 2019*

only thing that works consistently is the watch.  The pedometer works whenever.  Had 79,66 steps on it Mon, went to water aerobics class (1hr) & checked after, no steps added.  Not even regular steps from when I was done to when I went to bed.  Sleep monitor is same.  One night shows 15 hrs sleep, next day shows 15 mins for the night before.  I am returning the watch.

     I recently bought this watch, and as someone who studied materials science and engineering, I was really excited about the technology and love the fact that the watch uses a thermoelectric material to charge from your body heat (temperature differential across the back of the watch which is contacting your skin), which is energy efficient and removes the need to charge the watch at all or get new batteries regularly!  The watch has the standard fitness and sleep tracking features (there is a video below showing toggling through the watch features), and it is great that it even tells you how much power you are generating (included several pictures of the watch below and also a picture of a page from the manual showing how the watch charges faster when you are active and the air is cooler).  I really like the watch user interface (looks good and is easy to figure out) and surface finish; the watch itself has a relatively light but substantial feel to it, which is great for working out, although it is a little large and easy to accidentally hit.  The app is pretty easy to download on your phone and sync with the watch - I should tell you that the app has only the most basic features for a smartwatch fitness tracker, but it gets the job done.  Also, the app works with my iPhone and any Android phone, but if you have a Windows phone, unfortunately there is no app available.All in all, this is a nice product - awesome technology, easy to use, and a good look and feel to it!
