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 would like to know too, I am currently using the Colmi Rings R9. Tracks well but the app is not good deletes data and cannot change or add sleep and menstrual data.

Get a Colmi ring on Ali. It tracks basic things, zero capacity for notification, only $15.

I brought the R02 from tiktok for £13 including delivery as a trial after seeing a colleague using it. It was much better than I expected, felt nice to wear. I tracked lots of walk and some strength training. The ring has held well even with wight lifting and other stuff, I didn't take extra care bu
