A Rock Solid Mount!A well made and great performing suction mount for the action or other cameras. This K&F Concept mount, like the other products I own from them, is made right. They use top quality components to make a great product that lasts, many of my K&F items are years old and suffered lots of abuse yet still work well.The suction cup works well on most any surface, these are designed to be used on smooth surfaces, but as you can see in the photo, I use mine on a number of different surfaces that are far from smooth and flat. The dashboard in the picture has a textured finish that other suctions cups, even those with adhesive bases, fail to stick too. With this mount, I can dust the dash off, press the mount down slightly and give it 2 or 3 pumps and it grabs extremely well! I can drive down the roughest of off road trails or smooth highways and this mount doesn't care it just stays where I put it. It is even more impressive to me that it holds in the hot Florida sun, where interior temperatures can reach over 150° in no time and other mounts just fall off on their own.The included magic arm works great, easily holding my camera where I want without even the slightest bit of creep over hours long drives. Again a very well made part, machined from aluminum with super smooth movement of the ball heads and strong clamping force with just a little force applied to the lever. The cell phone holder is actually pretty nice for an included item, even has a cold shoe that is perfect for mounting a small fil light. Overall this mount doesn't disappoint,is super easy to setup and use, is priced right and provides a rock solid base for my videos.
