Review on JL Safety EZ Flex-Port: Secure Black Holder for EZPass Flex, Standard EZ Pass/I Pass – Fits Various Boxes – Made in USA with Patent Pending by Jay Huang

It holds my old FasTrak transceiver very well on the windshield without leaving any sticky residue. The suction cups only came off once but that was when I first bought it. I probably just didn't fasten it properly at first. It has now been in force for several months. / Adhesive tape, plastic to plastic, internal/external fasteners to replace it and allow you to work with this holder. Like this one: All-Weather Scotch(R) Fasteners, 2 Sets of 1" x 3" Strips, Clear (RFD7090). put in place.
