Review on Ultimate Fitness Tracker: Xiaomi Mi Smart πŸ‹οΈ Band 6 - 1.56'' Offers Unmatched Features and Performance by Mateusz Cieciora ᠌

Revainrating 5 out of 5

A very high-quality product, I take it not for the first time.

I measured my heart rate with this bracelet and a garmin chest heart rate monitor while jogging. The bracelet was set to continuous pulse measurement mode. It turned out that with a pulse of 165, the bracelet shows 125. At the same time, it is accurate at low pulses. The error at high frequencies is either due to the insufficient frequency of the optical sensor, or to the software algorithm for averaging heart rate up to a minute, which cuts off the maxima. In general, this bracelet is not for training.

Pros
  • Holds a charge for a long time; Interesting statistics of heart rate and sleep, motivates for healthy living; Works without glitches; Accurately measures the pulse up to 120 and the level of O2 in the blood (there is a nuance in the pulse - see Comment); You can upload heart rate statistics with minute values Many additional functions: training, stress, breathing, control of the camera and phone music, etc. An interesting option is to enter the VTB application online using a bracelet (bluetooth tag)
Cons
  • Inaccurately measures heart rate above 120 and does not allow you to get RR intervals
