Now for the good:
-The Suction cup is not made of ordinary rubber but very adhäsivem silicone as we know it from Fusselrollen! sticks actually already without the actual "suction". When dirty this area can be rinsed clean easily under water.
-In addition it is under finger pressure by a lever, which in addition generates a suction effect! The adhesive surface is thus an adhesive sucker ;-)
Now for the bad:
-The Re-laying lever not locked !!! definitely not! Under lightest vibration can watch how the button flips back of its own accord! I faith- very annoyed about it, I have this thing at home immediately dismantled to look at what is out there designed! Three small plastic tabs to slide during the rotational movement to a higher ground level and keep the sucker vacuum / vacuum pull the suction cup or less high. Since this is there but to "flat" surfaces is without then lowering a zugleiten- the button turns back. This is Reinforced- by an additional coil spring is to hold the button to power. This stretches the Drehbewegung- and soon radio frequency energy eintreten- slides back the button!
Have a small Dremel detents gefräst- on the plains and then it works perfectly! But who wants that advance machen- also you have a little tüfteln- around the part to reassemble. Is not easy!
-da the actual arm quite long and also on a soft, centrally attached Gummifuß steht- is the object to be supported, mostly a camera, but strong in vibration. For cars not so bad, because they are so well-sprung and himself rather swing muffled. For example, motorbikes with harder Schwingungen- (since the mass of a motorcycle's much smaller!) Therefore not gebrauchen- itself with best Verwackelungstechnik not! Dissolves here on top of Saugfuß- flies the following traffic camera in the Windschutzscheibe- The face of the last camera recording I want to see then like ;-)
Conclusion:
in buildings or cars- there geklebt- on smooth surfaces super - even if the lock, which actually is not present solves! So also stated on its own if you have thoroughly cleaned the feet under water. By pure Adhäsionskräfte- without suction In the car falling off is also not so bad.
Inappropriate all outside, on moving objects with harder stronger vibrations unsuitable and too risky - from the construction deficiencies listed above! Also not to Surfbrettern- because you A: do not know if the Cam floats and b: whether one when she swims, Ocean auf'm again findet- because that is pretty big ;-)
