I bought it for my boyfriend for Christmas and he's been wearing it all day with no problem, I found myself reaching over and spinning the ring, so I'm buying myself one. He says its comfortable and works well. When he first spun it it stuck a lil but after a couple of turns its smooth sailing.
I bought myself one and it has a poor time spinning and makes a god awful squeaking sound, so i guess each ring is different, I'll try to find something to make it twist better but it looks pretty.
The poor spinning was fixed with running it under hot soapy water and no longer made the noise, sadly I have lost the ring when I was shopping, so I'm going to order a new one. Also the ring I gave my now ex is still up and running and has lasted longer than our relationship
