The suction cup sticks to the textured dashboard surface?
I would not have expected that.
Since it says that it can rotate for landscape use...Technical Details
Easy one-touch mounting system locks and releases the device with just a push of a finger
Extra -large strong suction cup attaches to the windshield or most smooth flat surfaces and is easily removable
Super strong suction cup can be restored to its mint condition by rinsing it with warm water and allowing it to air dry
Fully adjustable with 360 degree rotation for quick portrait and landscape views
No slip-grip securely holds mobile devices up to 3 inches wide
That is really nice, I am ordering now.
