My husband wears large rings and they are not always easy to find. This ring fits perfectly and he loves it. It is convenient and safe to carry, especially when getting on and off large vehicles. The last of these rings came loose after getting caught on something while working. (Avoiding finger injuries) There was a slight problem on delivery when the ring slipped out of a hole in the shipping envelope before delivery. They immediately sent another one and I received it within two days with no questions asked. That's what I call great customer service.
