I bought them for 3900 and this money is quite justified, for more they are not worth buying. It feels like xiaomi released this watch, sent it on a long voyage and didn’t bother with the software and just scored on it, unfortunately. They record sleep data, but not quite accurately, but + - this only affects the totals for the duration of sleep. In general, I do not regret the purchase, because I knew about all the disadvantages in advance and for such an amount you are unlikely to find a better option
