Smart Ring with Charging Case, Health & Sleep Monitor, 5ATM Waterproof, Multi-sport Mode

I like this ring as for the low cost it is reasonably accurate ,the only strange thing is i bought the r10 because it seemed to be the newest so was expecting it to have the most features however the r10 doesn't have skin temperature a sensor whereas the r9 apparently does, so that's disappointing

Seems to work after installing. Only time will tell if it's reliable. I'm happy for far.

Amazing ring for the price, it seems quite accurate, i love that i can track my heart beat and sleep. And the battery lasts multiple days. I don't really understand the "rxx" label, i don't get if it's better the higher the number, or if it's just the ring style that changes. Anyways, i bought two more r02 version because i wanted the smooth look, these rings are so cheap that you can do that. I'm not sure about the longevity, i'm guessing after a year or so of constant wear, they might start wearing out. Not bad. The app is ok, not too many features, but it syncs with apple health so i can view all the stats there. I can only view blood oxygen in the colmi app though... I think it's because i'm in europe.

I got two of these rings. I didn’t think they would be a sparkly as they are pretty for me but way too pretty for my husband. I will have to buy a different brand. For my husband.

Good battery and no sharp edges. App is easy and includes all i need.
