I love my Spiralizer! Especially for ONIONS - very few tears (but there are some, even with putting in the fridge) but they are so good next to roasts, and the disappear into soups/stews/sauces if you have fussy kids
I purchased this for peeling Potatoes. Not happy with it. The Potatoes have to be like Baking Potatoes to fit the width between the Spiralizer and the Core where you puncture the potato.
