Nite IzeNite 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!

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)

For keeping rings on. But also used to get keys off without trouble.

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.

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.

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.

Love Nite-ize for the quality of materials and functionality plus many of their products come in a multitude of sizes.

This is as good as anything in its product class. I much prefer this to the double-gate or yin-yang version from Nite-Ize that this is the same size as.
