When I was in the Roofing Biz I used to have to set up a 40' ladder, by myself, about 25 times a week. It sucked and I repeatedly requested a jet pack. Of course I never got one. I'm not sure if it is the recording, my speakers or the actual sound of the engine,but that thang don't sound too good to me. And it looks like it could only replace a my 4' step ladder. I'll stick with my Telesteps & LG for now, but I got my fingers crossed!
