It fails the suction cup

OK, I'll tell the same, this review refers only to the suction cup. I did not come namely the actual testing of the Cam (which as far as made a good impression), but this was also due to the miserable app, which also did not work ...
A dashcam stands or falls (here literally) with its holder. The holds namely NOT. And I do not mean. Cleaned surfaces, tested at the levels tested on the window .. nothing. I had no chance to move the thing to attach itself to somewhere. After they fell off within 2 seconds. And before comments come: I have different suction cup holder for Navi, iPhone, etc .. GoPro so I'm not too stupid to be positioned part.
I am happy for all where it goes, my was unfortunately produced only for the trash and not get a second chance. For the price a NoGo.
