Review on Smart bracelet Xiaomi Mi Band 3 Global, black by Abhey Abhey ᠌

Pulse measurement. They display the right heart rate while the subject is at rest and seated in a chair (measured 22 times in a row, 11 times with a finger and a watch, 11 with this device, alternating these 2 methods). Experiment result: 72.45 beats per minute on average, according to the bracelet (69-78) "manual" method: an average of 73.63 beats per minute (70-76) The difference is 1.5%, which is well within the margin of error associated with statistics. When measured manually, however, the spread is only 6 contractions, whereas when measured with a device it is 9 contractions. This suggests that the device is not measuring accurately. When measured while walking and other physical activity (not very intense): - in some cases does not measure at all - in another part shows obvious nonsense - in the third part, the results are plausible, but how much they correspond to reality, one can only guess. The device is not very practical to use as a watch because it is difficult to read in any kind of weather, even cloudy, and it is nearly impossible to view in direct sunlight. In addition, in order to view the time, you need to make a specific movement with your hand or press a button, which means that a "regular" wrist watch performs its function far more effectively. Even with the assistance of the internet, it is not simple to grasp everything that is going on since the user interface of the Mi Fit program, which is required for the bracelet to function properly, is not very convenient and is not very intuitive. Individuals with an IQ below 80, such as myself, may have difficulty operating the equipment. Installing the Master for Mi Band program, which features a more approachable user interface than that of Mi Fit, helps alleviate some of the issues that have been raised. Even though the Master for Mi Band was available, the "notification of exceeding the set heart rate mark" function could not be activated. This is inexplicable when considering the precision of the measurements; even so, it was not possible to use this feature.
