KeySmart Stainless Steel Carabiner Clip - Round Carabiner Purse Clip for Easy Access to Keys and Accessories - Quality Stainless Steel Circle Clips - Lightweight O Ring For Purses (2-pack), Stainless

These are a good size for an air tag kept in an air tag container and attached to our keys/fob. They're easy to open using your fingers, but not likely to open by mistake, and certainly not on their own. They seem sturdy. We've been using them for about 3-4 months now, and have been very pleased with them. I can think of other uses they could serve than on a key ring, but that's where we use them right now.

Decent quality and stainless which helps. Also narrower diameter than a lot of others that are too thick for the holes on many devices

About a week after I got these, my house keys dropped off my keychain. OK. Gotta be more careful. This morning the other one just snapped while I was opening the store where I work. Keys flew. Had it happened elsewhere I would have lost keys. Unreliable product, cheaply made. Comes open too easily even if it doesn't snap completely.

This is an excellent compromise between rings, which are a pain in the butt to put things on or take them off of, and larger carabiner style which just 'leak' everything on them all over the place. This has been great for keeping my car fob, mail key, house key, and various keys without just having them fall all over.

Works. What better praise can you have for a product? Have them on all my key fobs.
