Review on JL Safety EZ Pass-Port: Indestructible Holder for Mini & Old Size EZ Pass, I Pass, I Zoom, PalPass, FasTrak - Made in USA by Mike Burnett

Just got this to install my old EZ-Pass and it fits snugly and securely in this holder. It doesn't look like it will fall out of the metal clip. The suction cup feels solid, usually suction cups are too small and can't support the weight of what they are supposed to hold, but this one feels right. I hope this lasts for many years. 3M Velcro adhesive mounts are another option and I've had good experiences with them as long as the glass is properly cleaned. The good thing about this alternative is that I can remove it from the glass without leaving a dirty residue.
