I actually have one of those, but with my 50 year old aluminum ladder, it is not of much help.

My brother-in-law who was a general contractor for 20 years stopped by yesterday. He asked "That ladder is scary as shit isn't it?" He has been on it and knows just how wobbly it is. Then a miracle happened, he offered to let me use his ladder that is only a few years old. I would have asked him at the outset if he wasn't normally a colossal turd. If I had asked him to borrow it, he would have given me endless crap about how I shouldn't paint the house myself, that I should just hire someone to do it. If I could afford to hire someone, i would have!

But yeah, it helps make sure the ladder isn't going to go sideways, but it still bounces and wobbles with every move. I fear at some point the thing just might bend and collapse. Every time I climb it, I get that much closer to justifying the $500 for new one. But really, when do I plan to use a 32 foot extension ladder again? 20 years from now? Never? And where to store it? The one I have now lives outside on the ground against the foundation and has for its entire life. Not to mention that the $500 is going to supplies to rebuild the front porch that rotted off the house 20 years ago. Won't need the ladder for that!
