Very happy with my purchase and saw many possibilities for my holiday to Tenerife, but was a bit skeptical at first, sticking my 300 euro GoPro to the outside of your car, you are going to drive in the mountains with deep chasms and you don't want to see your camera disappear in there. Just to be sure, I attached a line to secure things, this was really not necessary afterwards, the ProMounts suction cup remains perfectly in place, even at higher speeds and many bumps. The image also remains very stable and you can put the camera in all kinds of positions, so that you get spectacular images. My experience with this product has been more than positive and definitely recommended if you want to safely attach a camera to something.
