I gave this thing to an elderly man who was sure that he was not sleeping enough. Now I know for sure that in general he has enough sleep and his pulse is also good during the day. That helped a lot psychologically. So I recommend to buy. 5020947045 Has some pros comfortable to wear, after a day you do not notice it. Accurately counts the pulse and quite accurately the amount of sleep, which is important. Steps, in my opinion, are overly optimistic. Well, I'm not sorry :) I did not fully like the application on the phone - it constantly hung in the tray and ate energy. But this may be because I have an old android - version 6. I bought it at the Huawai brand store, so while the bracelet does not measure oxygen, they promise a little later. Cost 2750 with courier delivery. In general, the purchase is satisfied. Some cons: A meager choice of dials and some of the items from the "settings" menu, I would prefer to see separate items immediately on the bracelet.
