Review on LMB Spring Finger Extension Splint by Roosevelt Weaver

I searched for a question about this product but did not find it. So I bought one and I'm not sure if it works. My ring finger is stuck and Ben is two months old. This swells on top of the skin. I want one that doesn't touch my skin. The one I have is not AA size. I have a question: does size B fit my ring on my right finger? I'll post the photos I'm using right now. The one I have is small and I prefer a longer tip. so it will stretch my finger. I spend so much money trying to find the right fit but most of the time I'm uncomfortable.
