Wanted to post a follow-up ref this mirror. The mirror and application are great. However, I have run into a problem whereupon I can not raise the mirror without the set screw damaging the bracket. It appears that the set screw is just a tad too long and does not fully allow for clearance. At this point, the unit will no longer screw into the base for a secure fit. I have sent a note to PTM Edge to learn what if any actions they will take to address/correct the problem. Keep you posted.
