Review on 💓 Mio Slice Heart-Rate-Monitors: Sienna, Small - Enhance Fitness Monitoring with Precision by Pin Chun Lin ᠌

I am satisfied with the bracelet, better than Miband, when running, the heart rate showed exactly, I compared the readings with a chest sensor, it vibrates when making calls and SMS. There is no alarm clock in it, but it would not interfere very much. Its pros: Accurate heart rate measurement, almost like harmin measures steps, the error is very small. Cons: In sunny weather, it is very hard to see what the screen on the bracelet displays.
