I bought these so I wouldn't have to worry about cheap nylon straps dry rotting and falling apart leaving my cameras in the mud. While these do work, I will not be buying any more of them. Its a simple design, tree hook with an end smashed flat, hole drilled and small 1/4-20 tee handle bolt attached. The reason I don't like them, the only thing holding the bolt and the tree hook together (without a camera attached) is a small black C clip. What I found very quickly after opening my package was that those C clips don't stay on the bolt threads very well when you are trying to thread them into the bottom of a camera. I lost 2 of my three before I ever got a camera mounted. A for effort but its more like a participation trophy than anything else for Moultrie on this one.
