I have been wearing Groove thin rings for a number of years now. I have a physical job and an active lifestyle. I have worn out 3 rings so far, but have never had a problem getting a quick replacement. They stand by their products. The customer service is excellent. Even though I have worn through the rings, I would not hesitate to recommend them to anyone. In my opinion, they are still by far the most comfortable and attractive option on the market. (My husband has had a thicker men's ring for the same amount of time and has never needed a replacement.)
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
