Light / Reliable / Excellent autonomy

For the price, I am rather surprised at the quality of the bracelet. The bracelet is very light, and we forget that it is worn. The battery life is excellent, since it lasts a full month. I synchronizes once or twice a day with the iphone, and it vibrates every weekday morning to wake me up. The counter seems not reliable and quite close to reality. And the indication of its sleep cycles is interesting.

The application on the iphone, it's "Mi Fit" is all in English, and it syncs with health function of the iPhone. For me it is the perfect bracelet. See if he's okay keep in time (I've had one month when I am writing this review).
