I've been using one of these (same brand/model) for several years now, though I bought mine at an auto parts store. This is more of a "long term" review. I have the black one.
I live in PA, and use it with the EZ Pass tag we have here. I have no issues with the fitment of the tag in the holder; it fits great, and does not rattle at all. The holder then uses 3 small suction cups to adhere to the windshield, and I place mine behind the rear view mirror so that it's out of sight and does not create a blind spot. I have no problems with it failing to work properly when secured that way. That's not to say there aren't any problems, however...
My car is kept outside year round, and is a daily commuter. Being in NE PA, it sees all weather, from sub zero temps in the winter to over 100 degrees ambient in the summer, and everything in between. As a result, the included suction cups have yellowed and become less effective over the years, being exposed to so many temperature variants. That, in and of itself, isn't really a big deal, but it does mean that the tag regularly falls off of the windshield, hits the dash, and bounces somewhere in the car. Sometimes this happens while driving, causing me to have to fish around for the tag so that I can get through the tolls, and sometimes it happens while parked. Sometimes it's a result of the heat, and sometimes of the cold. Sometimes, the cups won't stick due to condensation on the inside of the windshield. Fortunately, it hasn't damaged my dash at all, but for those who have expensive nav screens and whatnot in their dash, falling objects could be a problem. So, that's problem number one.
Problem number two is even more prevalent, and contributes to the falling problem, and that's heat. In the sun/heat, the plastic melts. It doesn't melt where the tag slips in; rather, it melts where the suction cups attach to the tag, turning those points into a hot, gooey mess. This results in two things: first, the holes that the suction cups go in become enlarged over time as the plastic continues to melt, day in and day out, which contributes to the holder falling off of the windshield more often since it's not as secure. Second, because the plastic becomes a hot, gooey mess, the holder will fall off, land on a seat, and the melted plastic will stick to the seat, making a mess that needs cleaning, while the suction cups will remain stuck on the windshield. This requires you to reattach the cups to the holder, further deforming the melted holes since the plastic is usually still soft.
The third problem is a minor one that most people won't encounter, and that's that the design of the holder (using 3 suction cups) doesn't allow it to be used on curved surfaces. This means that I can't stick it on the inside of my curved motorcycle windshield on my sport bike. If it were the 2 bigger suction cup design, I could rotate it and mount it vertically, but the 3 small suction cups prevents it from working like that. Again, not a problem for most people, but fellow riders know that digging for an EZ Pass tag while riding through the tolls is a huge pain, and potentially very dangerous, so it would be nice if one didn't have to think about doing that. Even if I could stick it on the bike windshield, the thing is so deformed from the heat now that I'd be afraid it would fall off while I'm riding, and that would really make for a problem.
So, in conclusion, it works, which is why I give it 3 stars, but it fails to withstand the test of time and is very susceptible to temperature/weather conditions, which is why I can't rate it any higher than that. I have since read of acrylic holders that supposedly do not melt; given the choice, I'd definitely go for one of those now, as this model certainly has a limited lifespan.
I bought this product because I didn't want to put the velcro on my windshield. Plus we don't use the ez pass that often. It has been great so far. We are able to easily stick the ez pass on the windshield when we are going on a trip and easily able to remove it when we are done. The one downside came this summer in the extreme heat. We put the pass on the windshield to go to the beach and didn't take it off, as we would be driving to Boston soon after, and the extreme heat caused the plastic to warp and melt. I need to buy a new one as it is too warped to properly mount. I would highly recommend that you remove it from the car during extreme heat. Or at least remove it from the window. I still really like this product!
