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

i have a Colmi R09 and R02. 09 is slightly more accurate, but battery lasts about 2 days. 02 is a bit less accurate but "good enough" for me for sleep, activity, and exercise tracking and battery lasts over 4 days.

I have a colmi R09 and R02 for over a year now. I first purchase the R02 it worked great except the gold exterior is scratching away but the app and accuracy have been great as I have compared it with my Apple Watch.

I have a Colmi R02. Battery lasts 3 maybe 4 days. Activity and Sleep tracking is OK. Less accurate than Huawei Band (which is less accurate than Apple Watch). Ring is bulky and leaves an indent on my fingers. Also fingers unable to close together when straight. For the cheap purchase cost it is defi

I have a Colmi R02 that I got off of eBay for $25 shipped. It's my gateway to other rings and I recommend it. The RO2 doesn't do steps. Not that i have seen. I will go back and check again. I still like the silly little thing and it's going to my Wife when my Fitaos R05 arrives this week.

The most precise when it comes to steps is Samsung. One is as good as the other, even old models. It marks you as taking a few steps too far if you gesture a lot even if you're standing still. The Balance was fine until they updated this spring. Since then he started counting to 10 before leaving. T
