We tried the spiral vegetable slicer. We used a potato, which is a tough one. As you can see by the pictures, it worked fine. I think it will work much better when we get used to using it. I will try it on some full sized carrots and other things too. My wife and I enjoyed trying to use the spiral vegetable slicer, it worked perfectly. The cleaning brush made it much easier to clean it. Good addition to make the job easier.
