Thank you for taking the trouble to read through my review For all those who don't feel like reading through everything, I'll write a pros and cons at the end. Today I would like to write my personal opinion about the K and F Concept suction cup mount, which I was able to test as part of the Vine program. This doesn't affect my review in any way. I hope I can help you decide for or against the product. Since cameras sometimes cost a small fortune, I am always careful when I attach them somewhere with the help of accessories. Especially the attachment with a suction cup was never familiar to me here. I have to admit that the suction cup of K and F proved me wrong here. It is very easy to use. 1. Clean the surface on which the suction cup should be attached 2. Place the suction cup and pump with the pump until the white stripe in the suction cup disappears. 3. Install accessories and have fun The two rubber quick-release handles make it easier to remove the suction cup. If you squeeze it together, the suction cup comes off and you can remove it. When attaching and releasing, the accessories should not yet be attached to avoid accidental damage. Thanks to the white safety line on the pump, you can also see from afar whether the pump is starting to come loose. I've tested the mount on various surfaces. These included window panes, cars and even on a normal wooden door. Even the door had adhesive force (here, of course, make sure that the door is smooth and that no air can get under the suction cup. There are many ways to attach accessories on the top and sides of the suction cup itself. The suction cup also includes a small Magic Arm, a mobile phone holder, an ActionCam holder, as well as two rubber sealing rings, a plastic cover for the suction cup and two hexagonal keys. Pros: + Very high adhesive strength + Easy to use + Sticks to all smooth surfaces + Many ways to attach accessories to the suction cup Thanks for taking the trouble to read my review. I hope I was able to help with the decision making process. LG Nicolas
