I bought the Rhinokey to replace a different folding keychain, and after using it for a few weeks, can say that I would 100% buy again. Slick idea to have the box configured to make the assembly with your keys easy.. this was very fiddly and difficult with my previous keychain. I like the fact it stores keys at both ends (enabling a thinner profile), and the bottle opener has already seen a lot of use. I have a couple “non standard” shaped keys which made it a bit tricky to optimise the arrangement of keys, but worked out in the end.
