Crap... sorry bout the bad luck. I think I had those in my save for later cart. Deleting nowI bolted one on and just as I got it don't I seen it wobble. So I thought that was strange, so I taped on it and it shook. Not much, but more then I liked so I taped on it again and it broke off. Got looking on Amazon at other comments. There was only two. Both was about braking off.
