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.
