This is by far the most powerful food processor I've had. My test is always to see how smooth my humus gets and this machine passes with flying colours. So far, I've made several different kinds of spreads using a variety of beans and vegetables and it took less that 2 minutes in ever case to make the smoothest spread imaginable. Having different sized bowls also helps when you just want to make different sized batches of food. Mostly, it cleans up in a flash (there is one cleaning issue I mention later).
In order to find some cons I really had to get picky. I kind of wish there was an additional slower speed instead of just "on" and "pulse". The blades move so fast that it can sometimes not mix up your ingredients all that well. You have to keep scraping down the sides. Also, with the way they've designed the pusher/plunger you end up having to do a little extra cleaning. The plunger comes apart into three pieces and unfortunately all 3 pieces get dirty when you're using the machine so there is a little extra cleaning once you're done. And lastly, it doesn't deal with liquids as well as my immersion blender. it doesn't puree soups to a true liquefied state. It got close, though. Like I said, I'm being really picky.
