Has anyone used one of these devices? If you don't know what they are, they are a ball head you mount to a flat surface using a suction cup. I want an easy way to mount a DSLR to my kayak. I picked up a Mini Camera Mount today, but I'm thinking of taking it back because it didn't come with the height extender like it should have. I also don't think I will be able to reach the camera because it's going to be mounted too far in front of me. Just wondering if anyone else has used one of these products and want to know what you think.
