Review on Smart bracelet Xiaomi Mi Band 2, black by Virot Wrintharawet ᠌

Disappointingly, the functionality is lacking. The function that monitors your heart rate is of no value. Because I run on a frequent basis, I thought it would be a good idea to monitor my pulse, but it doesn't seem to be working. Only when the person is completely still can the pulse be accurately measured. It is not quite clear why these heart rate monitors need to be in bracelet form, with the exception of patients who are immobile. Only chest heart rate monitors are capable of providing a reliable reading of the pulse during strenuous physical exercise, this is the overall conclusion I got to after conducting my research. Either the wrist is lying or it will not measure. Nonetheless, it is important to note that the bracelet has the capability of using a heart rate monitor when tracking the phases of sleep. Yet, monitoring one's sleep is not nearly as useful. Sometimes the recorded sleep is extremely close to the reality, and you can see how much fast-wave sleep you had compared to how much slow-wave sleep you got. There is a correlation between the length of time spent in non-REM sleep and how sleepy a person feels. When you get more slow-wave sleep, you'll wake up feeling more refreshed. But, the bracelet does not always tell the truth; on one occasion, it stated that I went to bed at 3 a.m., despite the fact that I went to sleep precisely before 12 a.m. The outcome of monitoring sleep is that you are free to experiment, but it is not recommended that you purchase any kind of wristband for this purpose. Vibrating alarm. This is the part that appealed to me the most! It is a great relief to be roused from sleep by the gentle jingling of the bracelet rather than by the blaring of the music coming from the phone. It is important to have a bracelet for this reason. But even in this instance, there were obstructions present. It is necessary to tap on the alarm clock really forcefully in order to turn it off. It would appear that this was carried over from the prior model, which did not have a touch button. If you click the touch button, even accidently, or if you just oversleep the initial signal, the alarm clock will continue to sound every 10 minutes for another 3-4 times, and there is no way to stop it! You are working, but the alarm keeps rousing you from your sleep. To tell you the truth, it's rather distracting. The discussion will continue in the comments.
