There were a couple of things I really didn't like about this chopper. The main issue being that it wasn't very easy to chop with unless I sliced the vegetable in small pieces prior to chopping. Even the size of a quarter of an apple was tough. Then there was the problem with the middle piece (the actual chopping plane) coming up with the lid after chopping. My husband was using it one night and the plastic broke in the corner where the lid attaches to the bottom and rendered ours unusable. I love the design, I only wish it were much sturdier.
