To anticipate: This suction cup holder is not comparable with the many similar designs with significantly smaller suction cups and simple single-lever fixation, which also require sticky surfaces for attachment. This is a professional-level system — as shown by the specified holding weights of 60 kg or 40 kg vertically. The base of the bracket is made entirely of solid metal, and there are a variety of mounting options: numerous standardized 1/4” and 3/8” threads all around, some even with additional fixing holes. This clearly meets professional standards. In addition to the very high-quality small Magic Arm already included, almost all common grip elements from the photo, video and lighting sector can be attached. Thanks to the robust, ingeniously designed and excellently manufactured suction pump, which creates the negative pressure in the actual suction cup, the whole thing is bomb-proof and absolutely reliable. The decisive distinguishing feature from cheaper systems that are more intended for amateurs or small action cams lies — in addition to the massive metal mechanism — in the significantly larger contact area of the suction cup. The correspondingly large volume of air that can be extracted creates an enormous contact pressure. I would also confidently entrust this system with a more expensive smaller system camera with lens when driving outside the vehicle (however, wherever possible: with safety ropes
