The cones are sharp with many to choose from. The locking part of the 2 part pusher is annoying. Some food slices can get stuck in between parts without being ejected nearly wrecking the tool. My comparison to a popular stand mixer attachment this portable product is difficult to use and underpowered. Its past the return policy and I'll just use it for softer veggies and maybe try some chilled cheese grating. The plastic stains gross with carrots. Otherwise the product is good and functional if you have nothing to compare it to.
