I was going to try it out last night. I poured water into the reservoir(sp?) and it leaked out the bottom. I checked everything for something I could fix, but it needs to be returned. Maybe I can find another one somewhere. I never heard about using the car engine to heat food, very interesting. I suppose we have all at least thought on a hot day that an egg could fry on it--not that would be good for the car, of course.
