Cheap and light
Cheap fitness tracker. Bright color screen. I liked the clip on the strap (compared to buckles on watches). Snap-on contact charger (not wireless). I had a bit of difficulty getting call and message notifications to show. Lightweight alternative to full-featured smartwatches (note, this is not an Android Wear based bracelet, and there are no "apps").

the display is not good you can look at the pixels when you swipe ...
Is hard to download the app because it's not on the Playstore, you have to downloaded from the internet and change a lot of security setting on our phone, the display is not good you can look at the pixels when you swipe it, I could receive calls notification but never SMS notifications. I just returned, not happy at all.

Easy to use but weak instructions and it quit working.
Bithealth device stopped charging after about 3 months. Looks like one of the two charging contacts lost its plating.

It has a nice color display and works just like a fitbit
It has a nice color display and works just like a fitbit, but at a much more affordable price.
