Query: I can use a mandoline . . . and this one is not good

I received this mandoline for Christmas and immediately put it to work cutting an apple. I could not slice with it, and it was a mess. The next day I tried potatoes, and little plastic bits chipped off in my slices (actually, chunks) as I tried to get it to work. Then last night at a cooking class, I used a simple, cheaper, plastic V-slicer, and it cut potatoes like they were made of cotton candy. Several cooks at my table, all first time mandoline users, had no problem slicing apples and potatoes with that mandoline. My conclusion - my technique was not crappy, this MIU mandoline is. Luckily I could return at no charge and pick up a Borner V-slicer Pro just like the one we used in the cooking class.
