Query: Nice Idea, Piece of Junk, Poor Service

These ladders are quite ingenious. A very simple plastic fitting and steel pin locks the sections together as they are extended, and they progressively collapse coming down. I've had 2. Each lasted about a month of very light use. Soon one of the locking pins won't engage and its useless. The first one I sent back and they sent me a re-conditioned one. Another month, the same thing. I've called. They won't give you a drawing of the mechanism to try and fix it or explain how it works, and all the pieces are press-fit so it's non-repairable outside the factory. They basically said "too bad". After taking it apart I can see what I might have tried for a fix, but too late. They really are unrepairable and the company was no help. Save your money. Too bad there is no "0" star rating.
