but I'm happy that one went away
Ordered these after reading about them on some forum. I had a few sleep issues, the one bothering me the most was waking up with my ring and small fingers numb on both arms (due to some vertebrae problem). After four nights of wearing these, the numbness issue went away. It is now many months later and the issues have not returned. I still have my other sleep issues, but I'm happy that one went away. Only problem I have with these is that they either may come loose at night and fall off, or less often may tighten and I wake up with a finger numb from lack of blood flow. To be fair, I can't scientifically say that these indeed fixed the issue with the numbness, but the problem had occurred  for several months before trying the rings, and has been gone ever since that fourth day of wearing them. Still debating the other set for feet.
