I've used this ladder before, actually have a friends sitting in my garage now. I put up the Christmas lights with it this year and it was a breeze, my house has quite a few variable heights on the roof as well as some uneven terrain in the backyard, this ladder quickly and easily adjusts to each situation. I'm in for one, this is a good deal, cheapest I've seen it is around 216 at ACE Hardware typically it's more than that. There are also tons of accessories you can get, platforms, wallaways, and extensions for just one leg. Very cool device.
