Used in mi band. Come on! Tell me about the advantages and disadvantages of the bracelet!

Advantages: excellent waterproof, long standby time, and can be used for nearly one and a half months. Call reminder function and password-free unlocking are the most practical. Bluetooth has a good propagation distance. The most awesome time was when my mobile phone was placed on the dining table outside through a wall. Take a bath in the bathroom, and get vibration when power is on. There are new blue and yellow bracelets, and there will be other colors in the future, which is convenient to change and can be matched with clothes at will. Recording sleep quality and steps is accurate. In addition to walking and running, mi band APP also launched a laboratory, which can record the number of sit-ups and skipping rope at present, and other projects will be added in the future.

Disadvantages: Unlocking without password sometimes fails after upgrading MIUI 6 system, and Bluetooth needs to be restarted. If you don't reopen it, it will automatically work again after a while. It is very slow to open the mi band APP and synchronize data with the bracelet.
