Suggestions for a starter Smart Ring please!
I am using the Colmi R02 as my starter ring and it has taught me a lot. It was really inexpensive to get. At first it was my gateway ring until I got my Pebble Index 01. Instead it has become a learning tool to see what it can show me over even my smartwatch. So i do recommend it as a cheap way to g

Best Budget Ring
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.

Least, expensive smart ring
I would think the Colmi R02 would be the cheapest of the recommends.

Looking for an affordable smart ring - first time buyer!
I only just started with a smart ring and I read somewhere that a cheap ring is a good idea to test whether you’re likely to stick with wearing a smart ring during the day and when sleeping, checking your stats etc. I bought a cheap Colmi ring (r09 model) for less than $50, and so far so good.

New to smart rings

Talk me our of getting a Colmi ring
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.

One of the Colmi R series. I'm wearing a R02 right now that was recommended by this group and Ive been really happy with it. Even after having a slightly more expensive FITAOS ring. I find myself coming back to it. It's actually more comfortable than the other one. You can find them very cheap too.
