I love the power. The 600 literally blows every other blower I've used away.
I love the quiet operation. It's decieving at first, you don't think it's working because you don't hear the engine screaming behind you.
It's not to heavy.
I like the anti static mechanism inside the tube. I never get shocked on a blower anymore. Some of you know what I'm talking about.......
I don't think it's all that great on fuel though. Maybe it could use a larger tank.
I hate the gas tank cap.
Overall, I love them and by this fall the 600's will be the only blower I run.
