I think because this is brand new out of the box, I had a little trouble opening the container and popping in the attachments. I suspect that will get easier with each use. I decided to test a Sweet Potato on this bad boy, and it made perfect chips in very little time. I really love that this unit can hold all its attachments, so this can be easily stored away in my cabinet. The attachments are all very sharp, so I recommend using caution especially if you're trying to show your children how to prepare things. My husband and I both love this and plan to use it on our veggies and cheeses.
