I was looking for a Mandolin slicer that would last, and I found it! This slicer is made of thick heavy duty plastic, cleans easy, and hasn't warped over the last several months even with dishwasher cleaning. Super sharp blades store neatly in a plastic case, and the slicer body collapses for easy storage. This is a huge advantage over other slicers! A variety of blades are included which will cut any vegetable or fruit any way you want it. The adjustable knob makes it easy to get the perfect thickness. Each 'click' makes a difference of about 1mm, so you can be very exact with cuts. I use this most often to thin slice apples to make baked apple chips or thin slice tomatoes for homemade pizza, but I've used it for many other things. No decease in performance after several months of use, and the blades are still razor sharp. In fact, the blades are so sharp that it can be tempting to use the slicer without the hand guard. Don't do it. Save yourself (and your fingers) a trip to Urgent Care.
