Makes chips also cooks a chicken or chicken pieces. I used just once to cook 2 baked potatoes. You can make casseroles in it. Set the timer and variable temperature. The timer can be set from any time up to 2 hours. Then it shuts off itself. I just need space as two many gadgets. Instruction book is with the cooker. The equipment that is used for making chips has never been used its a new basket.
