Review on Fitness bracelet / smart bracelet M5 with pressure measurement, heart rate monitor, incoming call notifications, sleep monitoring, Android and IOS, black by Czeslawa Mastalerz ᠌

I bought the same Mr. on Aliexpress, for 290. I hooked to the smart without any problems, correctly counted the steps. Naturally, he does NOT measure pressure, this is a hoax. But the pulse showed. Charged at night, put it on at 6:15 in the morning and went to work. Until 12:00 it showed 95%, then the charge began to drop sharply. At about 17:00, it turned off and did not turn on again, did not accept a charge. I dismantled it with nothing to do. NO WATER PROTECTION in principle, just two loose pieces of a plastic case, with a gap between them. Therefore, even washing your hands in this bracelet is dangerous. The battery is some kind of non-name, with a microscopic capacity. The charge controller allows it to be discharged to zero, so that when it is discharged, it turns off for protection and is no longer charged if you do not disassemble and connect the charging directly. I summarize: even for 290 "it" is not necessary to take. More than 400. Don't buy, complete rubbish.
