This suction cup is different from the one known so far. I have a little hesitant because good 30 - just because Sony is on it. Suction mounts are available for much less. I bought it anyway. I am flabbergasted. While talking with a colleague I mentioned that the holder super glued to the car. He interrupted me and wanted to improve myself: "A suction cup does not stick to it is firmly sucked!" I smiled went to the car and took the thing. My colleague was quite amazed when he realized that this suction cup sticks yet. Also the acid test would have lost any vent mount after a few seconds. I have attached the mounting overnight at the painted wooden wall. The next morning it was still hanging there. At the car they bappt as screwed. Okay it leaves to paint and wheel Squiggle betray that there hung what but bisl clean un away they are. I am absolutely convinced.
