I like it! It does a great job of pulverizing the leaves into a fine, usable substrate.
Keep a screwdriver nearby when you use it, so when the head gets jammed up with fiber, you can easily pop it off and clean it out and get back to mulching fast. It doesn't like damp banana fibers (the midribs), they get stuck, but it still gets them to the point where they compost faster in the barrels, so I don't mind mixing them in if I'm out there shredding things.

It's built pretty good, it has a circuit breaker and is pretty durable, too. You won't be disappointed if you get one.
