I'm not even sure how melted dirt got into the faceplate threads, but that's what I found in the product I received. I was able to remove it after about 10 minutes of wobbling. Then, after another 10 minutes of wobbling, I was able to screw it back in, but it didn't hook onto the frame of the MR-16 lamp, leaving the lamp dangling in the bracket. I was disappointed and asked for a return/refund.
