I read some of the poor reviews but then thought how bad can it be at a sale price $39.95?
Well, I wouldn't recommend it to anyone, if KitchenAid gave these attachments away for free because they would steal the room for what could be less useless items. I tried the attachments on rutabagas, carrots, onions, and a few more vegetables. They made a mess of things, didn't cut them properly and I certainly could have done it faster by hand.
DO NOT WASTE YOUR MONEY or nerves on this.
The entire experience reminds me of a "As-seen-on-TV" purchase I made; except that product did work at first, unlike this attachment. It may work on cheese but that may well be it...and I doubt it.
