We never had a food processor before.  We were always intimidated by using them.  I was pleasantly surprised how easy the attachment was to use.  So far, we've used it to slice cucumbers and veggies for salads.  We've also made hummus with it.  I like it better than using the blending container because the blades aren't in the way when scooping out everything.

Cleanup is a breeze too since the container and blades were dishwasher safe.

If you have an Ascent Series or comparable device, this is definitely a must buy.
