Does anyone have experience with the Hobo Rotisserie?

I'm thinking of getting one for my Kamado bbq, and
wonder if it's worth it. Or for that matter, if using
a rotisserie in general is worth it. Seems like it
might take too long to rotisserie something that might
be just as good cooked on the grill. Any opinions?

Thanks!
