The chopper does as it claims however it takes little to bend some of the small squares in the slicing blade, i.e. with a tough piece of onion skin. Then it's useless.

I use this all the time to chop vegetables for my fussy eater. It's simple to use and easy to clean. It even goes in the dish washer. I would highly recommend this product if you have a fussy eater who like uniformly cut food. I would buy one again if this broke.
Everything
The cleaning tool it came with broke easily, which was dissapointing.

This chopper is inexpensive and seems to do a great job. All you need to do is peel the onion, cut it in half and press the top down firmly. It ends up uniformly diced in small pieces which would be difficult to obtain by hand cutting. Note that quite a bit of pressure is required to push the top down, but the results are well worth it!
Dishwasher safe, no onion tears, easy to use and clean
