My husband and I were looking forward to testing this out as we often cook together. Our first test was an onion. While I would like to say that it chopped it with ease, this was not the case. It took a lot of strength to be able to get through a quarter of an onion. Some of the pieces would easily break off while using. I do like the ease of set up depending on what shape you want it to be in. Will be trying on cheese next so hopefully it will work better.
