All 4 pins worked for about 3 strikes testing.then went to test again and only 2 work. That's the quickest I've ever seen anything go from fully working to half failing in the 48 years I've been alive. I'll edit if it happens to start working for some reason but I think I will probably be returning it. Giving it 1 star for shipping and 1 star that it tried to function properly however I think the 2nd star is questionable for a half failing part. It's possible I got a lemon, but I really couldn't tell you. I feel bad writing a negative review but the piece I got failed. They immediately sent out a new one that is fully functional
