TISUR Titanium Key Rings for Keychain, Side-Pushing key chain rings Split keyring heavy duty Keychain Rings for unisex-adult, bulk 3 Size Choices,...

These are nice and lightweight. A bit small and hard to get keys on and off.

Better design than standard key rings.

These are great little titanium key rings. the larger one doesn't fit my key fob hole, but the included smaller rings do. Happy with my purchase

These key rings are very well built but because of that they are also hard to open without using a lot of force which ends up hurting my fingers. I prefer their previous style of flat key rings since they were able to be held open with minimal force without hurting my fingers. However, I can see that they will resist getting bent due to the shape and geometry of the rings. With the flat style rings, I have noticed that if you try to load more than two keys at once that it will get bent. That is easy enough to fix just by bending it opposite direction, but I doubt it if you could bend this more heavy-duty style key ring without an extreme amount of force that's not likely to be able to be done with your fingers although. I am going to be returning them since I prefer the factor easier to use style and plan on getting those instead. However, I do think that there are people out there that could benefit from these heavier duty key rings. I could see them being beneficial if you are using the key rings for something that involves a lot of force or weight such as using them for attaching things to a backpack instead of keys to a key ring.

These rings work pretty well for keys, and so far I haven't had any issues with them -- they make it pretty easy to take keys off and on, compared to the more traditional spiral designs and they feel sturdier too. I did use one of the rings to hold my dogs tag to their collar, and unfortunately that ring didn't hold up so well, but technically it's still there so I guess it works well enough :p
