I've had to reset the suction cup once during one super hot day here in Southern Cali where leaving it under the sun all day seemed to warp the rubber enough to allow air to escape, but nothing was damaged.

2) one of the rubber x-grip post caps split and fell off

The ball joints are either made of hard rubber or rubberized

The Adhesion will not stay long in heat situation , the rubber will break down

If there could somehow be a thin "L" shaped shelf built into it to replace that annoying rubber thing, this mount would take over the world.
