Bought one of these a year ago. The single arm in the middle of the handle doesn’t turn out to be quite as stupid as it looks, but having two arms with the handle in the middle would still have been a better design (allowing a more versatile grip). Overall it’s a great tool though – there’s no way I could imagine single-handing a 3/4" sheet of OSB without it. I’ve carried heavy panels in a breeze with this thing, and it’s a much better arrangement for me than other panel carriers that grab the bottom of the board.
I got one when they had them a few weeks ago. it’s been a big hit at work. Easily lets me more stuff by myself that was taking two to three people without it. I’m in for another!
