It took me a while to get used to using this, but when I did, it makes great chips and potato wedges. You do have to add a little oil though to improve the flavour and also cook for a little longer than recommended.
My only gripe would be that it is a little small to produce enough chips for a family of four. Also it didn't come with a food divider? Which for me, given that I only cook chips in it, isn't a problem.
