I have one of those (not one Nick was shilling so I can't speak to the quality of his, but same idea) they're kinda gimmicky but it's actually really handy, I got mine because we have some tall trees on the property and I wanted to cut back the branches over hanging the driveway, and another that would drop fruit into my fucking fishpond every Fall, but I didn't want to be fucking about with a full size chainsaw while hanging onto the top of a ladder, and it makes it way easier than a handsaw.
It's a neat little tool, assuming Nicks isn't some knockoff Chinese shit, I respect him shilling that more than the Gold scam or fucking protein shakes or whatever the fuck he's doing now.
