I use it all the time!!!
I have the original oval shaped one, it doesn't even have a on switch. You just plug it in and when the light turns off it is at maximum temp. I could cook a couple of pounds of Trader Joe's Organic Chicken strips in 2 minutes.
My wife bought me the "New" model with the removable plates, timer and temperature control. I like the fact you can remove the plates for easy cleaning but it take 10 minutes to cook the same amount of chicken as the old one. When I'm cooking 6 pounds of chicken that's substantial increase in time. I can't go back to using my old one without hurting my wife's feelings.
Oh well it still is the best/fastest/most efficient way to prepare my chicken!
