It's very good for the money. So far, I've used it on onions, garlic, and pickled cucumbers, and it sliced them perfectly; you just need to cut them a bit beforehand into 3 to 4 large pieces. Don't expect it to slice tomatoes; that's not going to happen. Also, when I tried it on a green pepper, it crushed it instead of chopping it finely. Overall, a good purchase, but it's not very sturdy, so I'm not sure how long it will last.

Once you learn how to use it, it will do its job, the negative aspect is the size and the quality of construction, you have to push it close to its limits to do the job well.

It does what it claims. It cleans very easily.
I haven't had it for long enough to comment on the build quality (it doesn't visually differ in plastic thickness from other similar devices) and whether the metal/knives rust after some washes

I tried a tomato and it came out as if I had melted it. It didn't cut at all. I tried again with a little more force maybe.. but it broke...
