So I bought four of these recently and can't say I'm very impressed.

I took the ball out of one and tried to get it back in (I always practice with a BCR before putting it in so I know I'll actually able to put it in once it's in the piercing) and the dimple of the ball slipped and a line of the enamel coating was scratched off of the ball by the end of the ring. I hoped they'd be a bit more resistant to putting the ball back on to the ring, not pleased with the quality at all.
