Whole chickens don't cook well, they need to be cut up. Very handy for single serving of fries and fish sticks or chicken strips. It needs a lot of counter space for the lid when tending the food that is cooking. It does cook evenly. I bought one for myself and one for a friend. It has saved us both from not having to bend over to use the oven and risk falling. Also, not heating an entire oven for one small meal saves a lot on electricity.
