another broke labret/Monroe ring (I have both, and use these for both), it lasted about a week.
 I love the bio shaft, never had a problem with any of them (other than one other I got on here) before, and I also use small gems often, and don't normally have a problem with them either.
the same thing happened with this as with the other I ordered, the bio shaft was not strong at all and was not useable by the end of the week...
