I bought this 6 months ago and tried to do cucumbers, resulting in a sloppy mess.  Just tried it again with zucchini, thinking I would have better luck.  The guides are horrible, hard to follow.  For the special zucchini  instructions, i could never get the blade in, and then the spinning just tore up the vegetable.  No sheet, not one, ever.  could have done better by hand.  Don't waste your money or your time on this.
