My mum bought me the family sized actifry as an early xmas pressie in july and I love it! I use it all the time. You can cook home made chips in it as well as shop bought ones. I do my roast veg in it every sunday. Ive also made curry, one pot rice dishes and other stuff in it. The only thing ive tried in it that didnt work was spag bol, i didnt brown the mince beforehand so it stayed in clumps and (i add kidney beans to my spag bol for some extra veg) my kidney beans got mashed up which spoilt the texture.
If think if you look online you'll find loads of stuff you can use it for, its quick, easy to clean and I have had no problems with it so far and I use it at least twice a week. Hope this helps!
