Do suction cups REALLY hold on for very long?  The last time I used one; my plastic suction-tipped arrows didn’t stay stuck to the window for more than a second before dropping like a rock to the floor.  (picture a little indian shooting at every window in the house)

Are you constantly having to re-attach these car ones?  Does weather/temperature affect them?

Modern suction cups are fine at holding stuff perpetually, the problem is that leaving one (or even just the suction cup marks) in a car tells the thieves that you have tech.

I assume that you’re trying to be funny. Suction cups can hold well on very smooth surfaces. The arrows are not a good example: they don’t hit straight, for one thing, and the CG is way out, putting significant torque on the cup.

I have had problems with the suction cup mount for my Garmin GPS, which I mount on a “beanbag” base on top of the dash of my 2004 Prius, rather than the windshield. That makes it easy to remove and put out of sight, plus it doesn’t block my vision of the road.

In most states, it is illegal to mount anything inside a vehicle that blocks your vision.  You can even get a ticket for hanging stuff from your rear-view mirror.  From the pix on the NewerTech site, this looks seriously bad.

What is your definition of “most states”? Would TWO be considered “most”? I can find that California and Minnesota do prohibit putting anything on a windshield that obstructs the driver’s vision, but not any others. (The sites I consulted may be out of date, of course.) Do you know of other states? To me, “most” would imply much more than half, like 30 of 50.
