I bought this product several years ago from Sears and was using it on a 32-ft 2-piece fiberglass ladder that I had also installed the Werner leveler to it. As I was struggling with the monster that I had created, the Quick Click Stabilizer fell off from high up on me and deeply cut my arm. I still have the scar after maybe 4 or 5 years. I am lucky that it did not hit me in the head. Again the idea is good but don't over do it like I did. Use it on shorter ladders that you can handle easily and be careful, wear hard hat.
