I used this to chop carrots and onions for a soup I was making and I guess I was putting to much into the chopper.  I was filling the chopper about two thirds full, but found it only chopped what was on the bottom.  I moved things around and tried again, but what originally chopped pretty much turned to mush, while the rest finished chopping.  It's got a lot of power for such a little thing.  Next time I will put less in from the start.  Lid, blade and bowl are dishwasher safe which is a big bonus for me.  I would recommend for those willing to chop multiple smaller batches versus one larger one.
