The blade works well with soft foods (apples, onions) by cons it harder with eg carrots, potatoes. Again for that price it is expected a little better.
The cube system is a charm to cut fruits (I use it often to cut apples into small cubes to crumble), but is not perfect (it's still 100 times faster than cutting with a knife so we will not not complain)
Cleaning is very easy, it is happening under the water and it is cleaned. (He obviously does not expect that residues dry). The plastic that composes seems repellent and water bead on it.
