I actually bought them for my 90's. old father. It was quite difficult for him to exchange his keys for a normal shared key ring. This is the perfect remedy for his brittle nails. My only complaint is that they are quite expensive for the amount of keychains you get. I think a pack of at least 6 trinkets for $15 would be a lot fairer than just 4 for $15. When I think about it, paying just under $4 for a keychain is pretty expensive lol, but they're a lot easier to use. But the price is the only thing keeping me from buying a few other sizes.
