Pros: great time and work saver if you have a large yard with lots of leaves.
Cons: replacement parts. Had to buy a kit of parts just to replace one.
Works great if set up properly, but watch out if the plastic impeller breaks. They won't sell you just a replacement impeller, you have to buy a kit that includes the whole blower housing and all attachments, no matter what shape your current housing is in. My impeller broke when a stick went through it, but the housing is in perfect condition. As a result, I have to pay $180 for the kit when I really only need a part that likely only would cost about $20 or $30.
