I have a pole shark, which is the same principle as this with way less snaps and connections involved. Granted I am not in my 40's yet and I have only been around for 10 years, I cannot fathom life as a cripple type. I am a big dude and there are some very questionable poles out there I ran into especially in the midwest, Kansas to be exact that made me consider an alternative to the ladder on those tall poles that a 40 foot ladder was needed for. I don't use it very much at all but when it comes time to use I feel much safer climbing a woody woodpecker pole. But hey, thats me and my opinion, and of course we all know the deal about what opinions are like...but to each his own.
