First thing I noticed was this chopper is cheaply made the plastic is thin on it and even the metal chopping pieces on the bottom are flimsy.
The chopper itself the sides fold out for an easier time to clean this when finished using it.

I have only used this to chop onions & fruits.
As long as I get the outer layer off the onions first it works great.
If I miss some of that layer it tends to not chop all the way through.
I'm guessing the blade isn't quite sharp enough to cut through it.
Chopping is not consistent, meaning the pieces of fruit or veggie doesn't come out evenly cut at all.
However, the more you chop the smaller the pieces and then the more consistent they become.
