Yes, I have one on my radar detector. The product is a snap together shell...100 % clear/transparent....and snaps together like tupperware. The company that made these is out of New Zealand, and they made them to fit 4 or 5 of the most popular brands/models of radar detectors. I use a Valentine One, and it has been on top of the dash of my Goldwing 1800 for years, in every kind of weather imaginable. NO water gets through to my radar detector. NONE ! In doing a search, all I could find is this: http://www.dontgetcaught.com.au/catalog/item/5421341/5372286.htm Same idea...probably copied by a company in Australia.
