Review on 🚘 Convenient Toll Transponder Holder for New I-Pass and EZ Pass 3 Point Mount – Get Your Free Thought Designs (1 Pack)! by Jeremy Monroe

As another reviewer noted this holder appears to be 3D printed but by no means below par. I don't leave it hanging all the time, but I recently did a 30 hour trip and had no issues with the holder. The only comment I have is that the suction cup slot in the mount is not tight enough to hold the suction cups in the mount when they are not installed. So if like me you grab your passport when not in use, make sure all your cups are in place when you remove the holder. However, this does not detract from its capabilities as a holder and I consider it an excellent product.
