I had this product for a few days. It's really a very basic step counter with a simple bluetooth connection meaning it can buzz if your phone gets a call/text/app notification (no useful data displays on the watch screen). The sleep tracker doesn't seem to work and thinks I sleep for 3 hours longer than I do. That's all fine - it's a cheap product so my expectations were low.
I did, however, expect that I could run whilst wearing the tracker, however the rubber clasp keeps undoing and it falls off. This even happens when I'm sitting at my desk! I've just commuted to work via train and as I got off the train the watch came off my wrist and was lost on the track - after a total of 4 days of ownership. Seems like a pretty basic function to not get right.
