Well, my $5.00 dollar camera suction cup tripod mount mount came in today. Can't wait to test this baby out with my GoPro HD Sports Camera. So far mounting it to odd things in the office, it seems very sturdy! It actually held up my Canon 7D + Tamron 18-270mm Image Stabilized lens (Not that i'd try that setup hanging off my windshield).
Camera Saving Tip #1:
The first test everyone should do when buying a Suction Cup Camera Mount is to mount something in similar weight and size (not your camera!) and drive it around hard to see if it holds on well. Once you feel your product is up to par, then go for the real deal. I'm thinking Can Of Soda is larger, heavier, and not as wind resistant than the GoPro HD Sports Camera. If that don't fall off, i'm in the clear.
