I have a cheap one.

It is awful. Nuggs are brown on the outside and still uncooked inside unless you seriously defrost them first.

Its much slower once going then the deep fryer, but has no appreciable heat up time so for a small single batch works out about the same time. But the deep fryer wins out with multiple lots going thru it faster. Or you can power on the deep fryer between games or in ads or whatever at one time, and then after the game or next ad's go use it.

Everything will stick together unless you constantly open it and move them so the soggy touching each other parts are moved out into the open so they also dry out. Prevents doing other things while its cooking.

Everything cooks unevenly because the air is blocked by other things, Again have to keep opening it and moving things around.

The non stick on the cheap one is that useless non stick that doesnt work, and all the holding together metal is just chromed steal so rusts.
