I ruined my apple corer cutting potatoes for french fries. Tried all the ready to cook frozen ones but not happy with outcome. Never as tasty as fresh so I began my hunt. I chose this one based on reviews plus it included 3 sizes of blades for fries & hubby wanted thicker ones. The apple slicer was a bonus! Used the 1/2 inch blade twice now and fries are delicious! Tried it for sweet potato fries but I couldn't get them completely thru & afraid of braking a blade, I cut the potato into thick slices then thru the slicer.Best thing I cleaned a bag of brussel sprouts, mushrooms, squash & a slice of onion all diced in a flash! Clean up is easy as is swapping out blades! Planning on trying out other veggies & apple slicer soon!
