This makes my life so much easier.  Easy to clean and switch blades.  I can put together salads and stirfrys in 2 minutes.. littlerally that easy.  My only comPlaint is when I dice tomatoes the middle part gets full of juice and is hard to clean... maybe it's a user problem ?  I'm not entirely sure.  I use this nearly every day and is by far the sexiest appliance I have.  Worth every cent!
