One of my many fascinating female friends has one. She knows how to operate it quite well, but I perform the maintenance on it. I would estimate that it has between 300 and 400 rounds through it, and it functions just fine. I cannot see any unsual wear patterns inside either.
I haven't been around to see every round fired through it, but I have yet to see a malfunction so far. I'm thinking about getting one myself, since it is a perfect size for concealed carry, and the price is certainly right.
