Got this for my fiance. He's a mechanic and his tungsten carbide ring was causing issues since it's so durable. This ring, so far, has not gotten any scratches, or stretched, or reacted to any chemicals cars have, and has endured multiple hand washes.
Only thing he says is a negative is getting used to remembering it's silicone so when he brushes his arm or hair it snags. But other than that he is a very happy man and I couldn't be happier that he loves it!
