Bought a set of 3 and a 4th section this past summer. Went out this a.m. to hang a few stands for late OCT./early NOV.--wow, these things are the bomb. Rock solid, quick, easy to use, and quiet. Made hanging stands easy. I really liked that I could go down a section, and then rotate the one above around the tree to have a better angle getting the stand set. Once done, I removed them and now my security system is in place (unless someone is really motivated). Just an all around great product. If you don't have any, get 4 of them--the BEST $145 I've ever spent on bowhunting equipment.
