Nite Ize O-Series Gated Key Ring, Stainless Steel Split Ring Alternative, 2 Pack

I’m a fan of Nite-Ize products. These key rings are no exception: they’re solid and easier to operate than a typical key ring. The only thing is the opening is small (ideal for any key, but impossible for a key fob without a small key ring). My car’s fob didn’t have one of these small key rings on the loop, so I had to steal one from another key chain I had, which enabled me to add my fob to the key ring. Hopefully that makes sense to the reader. Overall, I recommend!

Good and sturdy easy to get keys on ring.

This does trap keys on it better than a conventional keyring, but the inlet for getting them on is a little undersized. My old model of Tile tracker couldn't make it on, but the newer model fits. Otherwise, it's sturdy and keeps keys on.

such great value for the price! there is no way your keys will fall off this ring because of how sturdy the clasp is. the size is perfect for a few door keys and one car key. it’s lightweight and easy to slip keys into but difficult to get out (which is what we were looking for)

These o-rings are easy to use and function well. The size is exactly what I needed, and they look sleek and not clunky. So far, my keys haven’t fallen off and the gate doesn’t open on accident at all.

Ingenious design for a round key loop. No more struggle trying to pry the tension loops apart and wind your key on. Simple to use and highly functional.

Works well enough for standard keys but the opening is too narrow for anything else. Slightly larger keys or irregularly shaped keys such as bike lock keys won't work with this ring.

These are quite sturdy - which is certainly what one wants. There is no give in changing the size (assuming "normal" handling). But this has its one downside. The opening is fairly narrow - some 2 mm or so - and nothing thicker, without brute force, will not slide in. So this may limit some applications.
