Cycleaware Reflex Helmet Mirror (Black) (Adhesive)

I have used these mirrors for years and the only problem I have had (other than finding them occasionally) is that the small plastic ball-in-socket joint where the mirror joins the flexible arm has eventually (after a LONG time) become loose. That was easily fixed by dipping the ball part of it in liquid rubber that is sold in hardware stores for coating things like metal tool handles. I can only recall that being necessary once or twice over the (maybe) 20 years I have been using these. They work so well and are so cheap that I would have just replaced it but for the problem finding them sometimes.

I love this mirror and have them on both winter and summer helmets and here is the reason why!
#1. My head never moves, rather my eyes can clance to the left (unless you live in UK where the mirror would be on the right side of helmet (then you would glance to right).
#2. I can quickly unsnap it when travelling and put the mirror/post in safe place and sling the helmet over my backpack to board a plane
#3. Its 50% less cost than others , Yes they have larger mirrors, but try to quickly take it off !
#4. Mirrors should be on your helmet, not on your handlebar for safety reasons.
NOTE: when I need to re-install on new helment, I remove the entire thing, clean off the gluish left, use Double Tape to re-apply the holder to the helmet.
