The bulge on the ring keeps my car's key fob from moving in circles. They are hard wearing and although they are titanium they should not rust.

These rings are strong and durable. They were packaged in a nice tin that only contained three rings, not the promised four rings.

This item is easier to use than regular split key fobs with a rounded profile. The end slides easily to the side and the low profile makes it a great option for small openings. The price of these little devices is a little high, but they are worth considering as an alternative to the open-end wrenches that break nails.

The product is advertised as being more convenient for attaching keys to a ring. However, I can't open it so it's very disappointing as I have arthritis and thought it might be a good alternative. It also came in a small plastic sleeve that was almost impossible for me to open. It took me a few minutes of curiosity before I finally opened it. I don't know why this packaging. The plastic case is completely superfluous. I would rather do without the plastic packaging. If you have stronger hands…

They are well made from "soft" titanium alloy and have a fantastic design. Why didn't anyone come up with this idea before? I was concerned that its "flat" design would not fit some of the smaller keys like the Master Lock, but they will fit all 18 keys, remotes and fobs I've used them on.

Watched them for a long time and finally decided to pull the trigger. Unfortunately I had to send them back. The biggest problem was their width: the rings just wouldn't fit through the holes in some parts on my keychain (pictured is the smallest version of the k22). When you look at them, make sure everything on your keychain has a big enough hole, especially for the "bulge" these rings have for your thumb. But to be honest I found them really harder to use than regular ones. With normal rings

Much lighter than normal key fobs and very strong. I love them and will order more. I would take the larger size unless it's for a key or remote etc.

It was a good attempt to alleviate what was already painful to get the keys but failed. It seems even more difficult to pull the key loop off and leave it open until you insert your key. To be honest, it doesn't spare your nails much. Also, it has a small ledge which I assume should help you open the key loop, which is nice but depends on how small the keyhole is for your key. It may not be possible to obtain a key to bypass the entire cycle.

I use them for keys and tags on my three Great Danes on collars. All three love biting dog tags off another dog and ripping off cheap clips. Was looking for something stronger and these seem to have helped.

I was looking for a replacement for a standard key fob that was starting to deform due to the amount of keys I had (and probably being in my pocket most of the time). ). All requirements were thus fully met. Although not smooth, it has a nice texture while being very durable.

This item is easier to use than regular two-piece key fobs with a rounded profile. The end slides easily to the side and the low profile makes it a great option for small openings. While the price of these little devices is a bit high, it's definitely worth considering as an alternative to the open-end wrenches that break nails.
