The spring release mechanism is not strong enough to handle everyday use. Mine broke after a couple months on my keychain, removing the key with the spring mechanism probably twice per week max. The design of the mechanism needs an upgrade.

This item is built sturdy for sure. I fine it a bit large not in circumference but a little difficult to fit all keys. the push in is quite sturdy and can be trusted. I think there are other rings that fit my purposes better.

Great clip that opens like butter.

These are both really cool and functional. Looks great anodized.

There's probably a million and uses for this ring. I'm using it hold different ring sets of keys. Less bulk. Strong and functional for my needs.
