Broke within 1 week of buying. I had to return. By broke-I mean the spinning peices on the outside came apart and fell off. For the week I had it, I liked it pretty well but it was pretty thick so if you aren't used to wearing bigger rings like this, its a bit of an adjustment. I bought it to help stop picking at my nails. I don't think I had it long enough to say whether it served that function or not.
