Got this chopper just a week or so ago.  It can handle a surprising volume of food and never complained.  It powered through 4 cups of baba ganoush beautifully (this isn't always an easy task). Nuts, onions, herbs-- you name it and this thing will chop it.   Prep work is super-quick now.  Need mayonnaise?  Done!  (The Drizzle Basin really works well)  If there is one complaint, it was that the top is a bit fiddly to attach at first, but it is getting easier with more use.  The two speed options make managing your rate of attack much easier, widening the line between chopped nuts and nut butter.  Cleanup is quick and easy!
