My experiences and opinions stem from my owning the alpha hang-on, ONLY. I don't know squat about their climbers.

Comfort, to me, is the number one criteria in purchasing a stand I'm going ot use a LOT. I feel like it definitely keeps me on stand, longer.

For that reason (alone)......I wouldn't own one of these stands. It is well built, quiet, adjustable, etc...

I could also never figure out how to set it up (with the climbing sticks) without working up a heckuva sweat.......NOR could I figure out how to set it up, safely (comparatively).

Just giving my opinion based on the one I owned for a short time (a short time.....for the reasons I cited).
