I purchased it because i was desperately looking for something that would ease my work of chopping onions and tomatoes. The Chopper is good for tomatoes but for onions i see it chopping 70% of onion piece. if you try to chop further the already chopped one becomes fine and the ones thats not chopped remain as it is... also, it gives uneven size of chopped onion.

Other thing is the fine pieces of onions gets left on the inner edge of the blade and you need to clean it under tap thoroughly... I would certainly not recommend it over hand pressed chopper that you get online and in store.
