The Xiaomi bracelet was released with the release of Xiaomi 4 in August last year. The price is 79. I bought the bracelet this year at the market price that Mr. Lei once again lowered. The initial impression is that the record is accurate, especially for sleep. Later, the mobile phone was updated to Android 4.4. It's possible to unlock the mobile phone, but I'm not used to not wearing a bracelet. The unlocking function is really good. Mr. Lei heard that he decided to develop the bracelet because it was easy to unlock. It has been more than six months now. Fortunately, I haven't lost the bracelet like others. The bracelet is really loose. Now I have changed the bracelet, but the workmanship is not good. The bracelet accompanied me for a summer vacation. I walked more than 10000 steps every day. The function of counting steps can be defective. People can walk without shaking their hands. It seems that all bracelets have this defect. The surface can be easily scratched. The surface seems to be made of aluminum, but we don't have to worry about anything without a display screen. Another is waterproof, so you don't need to take off the bracelet when taking a bath. Finally, millet bracelet has been integrated into millet ecological chain. If you are rice noodles and haven't bought a bracelet yet, you can buy one.
