I want to make sure people understand that I gave these 3 stars because it didn't work for my purpose. I tried using this with a bike handlebar action cam to reduce video shake. IT DID THE OPPOSITE. It actually made the video more shaky. Well, that might work well for a small camera mounted on a quadcopter, and that's probably what it's designed for. I'm not sure but it didn't work for my purpose. I will say that it is made from high quality phenolic board and the rubber supports are very strong and sturdy.
