Query: One star is too many

It pulverized the apples I tried to slice. Thinking that they were maybe too soft, I tried carrots and they sliced half-way through and broke off the rest of the way. The blade isn't sharp enough and the knob on the bottom, which is used to adjust the blade, makes whatever you're trying to slice get jammed and then break (rather than the nice neat slices I had hoped for).I bought it at Bed, Bath & Beyond and returned it. Had I looked for it here, I wouldn't have bought it, based on the negative reviews. (Had I bought it here, I would have had to pay return shipping.)
