I wouldn't be without mine. I've used one for years, and this must be about the third, always buying a bigger one each time. I now have a large, oval chrome one which easily holds a good-sized chicken, and can be left safely to cook for hours. If I'm using a cheap cut of meat, I put it on low and give it about 5 hours, sometimes more. My DGD and her boyfriend are hoping to find a flat soon, and she's asked for one as a moving-in present.
Do you still have all your own teeth?
