I bought this because my wedding ring was giving my finger a rash.  I believe it was due to some sore of bacteria and wetness build up underneath the ring, but I would clean my ring thoroughly but the rash kept coming back.  I finally thought I should just give my finger plenty of time to heal completely (because maybe the rash kept coming back because the skin wasn't healed completely before putting it back on).  I bought this to place on my finger instead while waiting for my finger to heal because its mage with surgical steal and has no indentation underneath where wetness can get trapped.  I wore this ring for a year and I just recently switched back to my original ring and my finger is fine so far (knock on wood)!  Im keeping this though so I can still wear something if I need to take my ring off for an extended period of time again.
