Review on TISUR Titanium Keyring with Side Pushing Design - Stylish Men's Accessory in Keyrings & Keychains by Simon Connelly

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 I can open the ring with my fingernail with one hand. While it hurts, it requires holding and twisting the ring with both hands, which I found much more tedious. Judging from the pictures I always assumed they opened up somehow, but of course they don't; You have to hold it with both hands while trying to toggle the buttons on and off. I gave it an extra star because they are super cool and I really wanted them to work.
