R02

I have a cheap Colmi Ring, heart rate, steps and sleeping is quite accurate, battery last 5 days and has been quite reliable, super happy for now. Cost around 25usd

None of the Colmi rings are accurate with regularity, but even a broken clock is right twice a day. The sensors that go into the Colmi rings (and other clones) are so outdated that they no longer have any real commercial value...which is why the rings are so cheap.

TRANSLATION: Colmi R02 drains battery Good morning community, I recently bought a Colmi R02 ring and the battery lasts less than 24 hours with all health options turned off.

I bought a cheap Colmi R02 smart ring from China. Battery lasts 4 days. Activity and sleep tracking OK. Far less accurate than my Apple Watch. Then I bought a Huawei Band (mini smart watch). Battery lasts a week. Activity and sleep tracking better than the ring, but still not as good as the Apple Wa
