Not a bad item, battery life is no where near what it says here. Even from out of the box. I would get 3 or so days max, one single day if I am interacting with it heaps. The app appears to be Chinese developed ( nothing wrong with that ) just means the features are limited right now and the english is a little clunky. Things I really liked, being informed that I have a call, text message/messenger reading and the health metrics. I really like the strap too, its like this neat magnetic thing that is really cool and is adjustable as you want. It is also quite cool looking. Things I didn't like: Battery life is average and the watch appears to forget its suppose to be talking to my phone sometimes. Putting the strap on was fiddly. I got for $30 on special and for that, it's actually quite nice. Just don't expect it to compete with a fitbit or similar. I like it and will use it for some time.
