Really fast and reliable. Reliable original products.Low price.
After that, I'm going to shop all the time at Gearbest. Thank you Gearbest. Xiaomi mi band 2 : Pluses: waterproof. Dustproof.
20-30 days battery life. Really cheap. A great intelligent group. He watches perfectly what he designed to follow.
Sour are: I realized that once I turned off notifications and only used heartbeats to monitor my stepper and my sleep / activities, the battery could last longer, so I noticed that integrating another application notification system could make the battery very low. I've been using this band for more then half a year. It's everything you should expect from Xiaomi. I've been using it with Motorola Moto g3, and also a Xiaomi mi 6, with which i'm still using it.
Heart monitor is accurate in about 70% of time (comparing with Lifepack 12 - i.a professional heart monitor), steps also seem to be estimated right. Would buy again :)
