Query: A good idea but not all that

When I bought my coarse microplane I saw this little doo dad next to it and thought, 'cool! something to save my fingers from the sharp blades of the microplane!'I took them home and tried them out together. You know how to expect a nice fluid grating motion when you grate things? This didn't do it.It would stick and jerk on with the plastic against plastic. Added on top of that you had to hold the stuff and the lid over the top of it. I was very disappointed and put this away and just used my hand.Yeah, I have to watch my fingers, but it's much easier to do than with this slider attachement.A year later it just sits in the cupboard, I think someone finally threw it away.
