My Nutri Chopper is so easy to use. I love using it for my onions. They come out perfect when I cube them! The slicers fit well into the chopper. I wish they were easier to clean by hand as I don't have a dishwasher. A sponge works, you just have to be careful.  I love the detachable cup for transfer to a bowl or pan and also for storing extra chopped veggies. Overall I would recommend this chopper!
