I used it to fix the GoPro on the glass of my car, outside, traveling and make nice videos of the landscape. Even by unfolding the suction cup arm exceeds the GoPro unless the mirror. I placed the cup on top of the glass, which still gave a little more room and a more clear picture where there will be the amount of the windscreen and a cover of the song in a corner of the image. The quality of the fixation is impressive; even in passing on Dane back, nothing moves. GoPro indicates that its fixation want to very high speeds ... but I have not tried. My goal was to make nice traveling, not to make me look like a rally driver.
