Super super

Ok

searched for xiaomi MiBand4 - offered is a so-called M4 band - Fake product... same design, same case, same optical appearance but : operation terrible, watch face changes constantly, tracking for sports delivers completely wrong data, device constantly disconnects, battery empty after approx. 3 hours... Simply JUNK 😡🤬 UPDATE: very friendly contact with support 👍 and quick remedy 😃 thanks to JoomTeam 🙏

It's quite good, not all the functions work or maybe I still haven't found how to activate them, the application that belongs to this cias is not very stable...all the commands are done with a sensor button

I love it so much It arrived without any defects thanks

I have uploaded it, it remains to come back with a review
