I have the support it used to attach the GoPro Hero3 the car. The suction cup holds this fairly well on straight as possible slices, on the paint the place already has fairly even (do not get it to attach the bracket to the side part of the back). However, a major drawback of the holder is the high resonant susceptibility. The further the GoPro is set from the suction cup away, the more extreme wobble the video on vehicle recordings. Therefore, I have decided on a 3-vacuum suction kit, which works for top.
Dropped the bracket is never but one should his GoPro anyway with an emergency cord secure (google: GoPro Tether) That goes with the simplest means and the camera does not fall on the ground, first and second, is not possibly disappeared in the forest)
