It is an interesting method. It looks like he has built a 5(?) step aider with foot stirrups on each end. On one side of each end is a J hook and opposite side he has an Amsteel daisy chain. He hooks it up, climbs up and into the stirrups then works the ladder up between his feet and then pulls the "bottom" and it slips loose. He then raises it up as high as he can and hooks the bottom up above his head and that is now the top. My only concern, and maybe it is unfounded, is the possibility of the daisy chain popping off of the J hook.
It's a neat idea. I did not quite understand the reason for the last part where he is hooking it up securely. Is it to serve as a gear hanger or does he intend to stand in the stirrups and not use a platform or a ring of steps? I'm not sure on that one. If I weren't completely comfortable with 2TC at this point, I might consider purchasing one.
The feeling I got from the two videos is that he intends to market these commercially, which is just fine. I'm guessing these are the introduction videos and at some point, he will provide purchasing information.
