I say I would recommend this but that comes with an IF.
I actually returned mine. This is a great attachment if all you need a processor for is to slice, dice, and shred. It leaves some residual stuff but other than the really expensive ones that is hard to get away from. The dicing insert is great though hard to clean.
I discovered I also really want to process stuff with a blade. You can't do that with this attachment. For me it was too expensive to have such limitations. I got a regular food processor.
If you just want to slice, dice, and shred though, this does the trick.
