Review on Smart bracelet Xiaomi Mi Smart Band 4 RU, black by Stanislaw Grzechnik ᠌

Revainrating 5 out of 5

The quality is at the highest level, be sure to try it.

Despite this, you will need to charge it once every week. In overall, the acquisition meets all of the expectations. I put every available feature to its fullest possible use. The accuracy of the heart rate monitor can be off by as much as eight beats per minute at times, but the researchers believe this is related to how tightly the strap is fastened.

Pros
  • In a store that does not have Internet, payment can be made with a bracelet. Your master card number is encoded in the bracelet as a backup copy. Monitoring the amount and quality of sleep can be done easily. The bracelet is compatible not only with the app that came pre-installed on the phone, but also with applications from third-party developers.
Cons
  • minus working time. A maximum of one week is available to me. Perhaps, but only if you deactivate the vast majority of the features and set the screen brightness to its lowest possible setting. It's possible that would last for longer. It is inconvenient to use the charging kit. Every time you need to charge the device, you have to remove it from the bracelet first. The fact that you can only attach Mastercard cards for payment is a significant drawback. And not just any banks, but only those on the list that the maker is able to support.
