Review on PanaVise PortaGrip Holder Premium Windshield by Mike Walters

On a clean surface this mount will hold up like a JB Weld! I used their other mounts with the same suction device to attach wireless logarithmic antennas to glass windows and when I was done I had to rip them off the glass. The secret lies in the ultra clean surface and maybe a little moisture on the suction cup. You should experiment to see what works best. This device can, in another configuration, support a full Canon DSLR with a 35-70 lens (that's it) on flat glass. I use mine every day in my van as a phone mount and it never lets go of the metal console during daily driving. The rubber pads on the handles hold my Revain case well.
