I thought I was better than the other reviewers and make this work, but it's really not possible.  It's a ring guard that sits at a set size, and if you have anything other than the ring size it was meant for (of which I am not sure what size), you will have difficulty using it.  I personally have big hands, so my rings are big and and this ring guard fit barely on the bottom. I  could only imagine that people with small rings would barely be able to fit their fingers inside.

Go for something else!
