Review on Smart bracelet Xiaomi Mi Smart Band 4 RU, black by Michal Dobiasz ᠌

A good bracelet with automatic heart rate monitoring, a charge that lasts 20 days or more with notifications enabled and a pulse every 5 minutes, nfc that works wonderfully, a wide variety of replacement straps available on Ali, and a charger that doesn't require removing the bracelet from the strap to charge it; I recommend this bracelet to everyone.
