Pros: Solid, hefty, quality item. Blades are still sharp after a lot of tough use. I had some hesitations about what size to get, but the small size is plenty big for most, if not all, situations.
Cons: Nothing major, every now and then, it can get quite stuck, requiring cleaning. A three level would solve this since there's less buildup of small particles, but if you want to save some $, it's a reasonable sacrifice.
