I wanted to make my own curly fries. This vegetable slicer does that! I used the 1/4" blade and found that you must use the pressure handle on the unit to produce the best cuts. You do end up with a vegetable core which some people have complained on other reviews that it ends up being waste, but that really was not a big deal to me. I tried cutting up and frying the cores, but I didn't like them so now I just throw the cores away. It's very little waste anyway. I did find that smaller potatoes produced tighter spirals, but the smaller size also produced a lot "waste" where there were just short curved shaves of potato. Larger potatoes produced fewer of the tight spirals and much more of the swooping long spirals, but they also produced less "waste". Using a combination of large and small potatoes produced a good mix of curly fries for me. I fried them in the deep fryer, shook some sea salt on them, and they were YUMMY!
Based on some other reviews, I tried making "zucchini spaghetti", using the 1/8" blade. I found a recipe online at steamykitchen.com where you basically BRIEFLY stir-fry the zucchini noodles and add sauce. The spiral slicer produces very long zucchini spaghetti "noodles" and I did find them to be somewhat difficult to bite off while eating (so just cut them short before cooking) but it really did produce a delicious, low-cal meal!
The extra blades store within the unit, and it's very easy to change them out. Just rinse to clean, and do it sooner rather than later to minimize staining of the white plastic. I paid $29.99 for this slicer and I am very happy with it!
