I have one. It has like double the power of a big backpack. It really moves the leaves which I have a lot of.
I have the six horse Billy Goat.

They do seem more effective than backpacks. Mine has a Subaru Robin engine. Starts easy and really blows the leaves around. I had to figure out that there is a friction lock on the control lever for the nozzle. Mo HP always mo bettah!
