I received the stack and snap, 10 cup food processor and I love it.  I made my vegetable lasagna so quick and easy.   The slice blade did a great job of slicing the crook neck squash and zucchini.  Then just flip the blade over to shred cheese.  It worked better when I put the cheese in the freezer a short time so it was very firm and cold.  There was very minimal amount of veggies not being sliced cleanly.  Making salsa was just as quick and easy using the other blade.  Just make sure you turn the motor on first to finely chop the garlic and jalapeno before you add the rest of the veggies and pulse it till you get the consistency you want. I especially like the fact you just stack the pieces and snap it closed.  No trying to line things up and twisting hard to lock.  I most definitely recommend it.  Very good food processor for the price point.
