I hated the way EZ pass mounted to the window. The Velcro turns color as time passes and its just gaudy looking. This mount allows the EZ pass to sit inside the car but angled enough to still be read by the tolls.
bicycle reflector mount
Mainly buy a cheap bicycle reflector mount off ebay, roughly the same circumference of your rearview mirror arm. Unscrew the reflector and add the 3M velcro. Cut the rubber tubing and insert into the mount that supposed to mount into the frame of the bike. Mount to mirror arm and adjust to towards window.
