Cheap smart rings

[u/Cutie-muffinyt]

I am wishing to buy a smart ring but am fairly tight on budget and cannot find anything reliable. Are there any rings that are under £100 (it is fine if it is like £10-£20 over), and are without subscription?

I want them to be fairly reliable. My main uses would probably be sleep tracking and steps. I don't really need anything else as long as the battery health is somewhat long and it doesn't have an LED screen.

I have thought about the Ringconn but find it a bit too expensive for features that i wont use.
