R02

I recently discovered the Colmi rings. I went with R09. I haven’t tried more expensive brands or those with newer tech. But mine seems fairly accurate for sleep. I’m happy and see no reason to upgrade for now. But if I do, it’s likely to be a Ringconn.

Which band did you get - interested to try one. Already have a Colmi ring and the data displayed on the stock band app looks to be very similar to what i get feom the ring. But for 23€, worth a go.

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
