I am satisfied with the purchase, on the aliexpress the bracelet came out with a good discount. The old Mi Band 4 is still working, I gave it to my child) Some pros: Big screen. Charging holds 14-16 days, but it depends on the included features. Some cons: Compared to Mi Band 4 (switched to 7 from 4 Mi Band), the screen slows down when you click on it, 4 lights up immediately, and then you have to poke more than once to see the time.
