I've had this crock pot for about a year and a half now and I hate it. I've cooked things on low and come home to find them boiling. However, last week I tried to cook something on high for the first time and after four hours it wasn't even simmering yet. It still has a burning plastic smell to it which is awful. I called Rival shortly after I got it and they told me this is normal. The meal I was cooking on high tasted of chemicals. I don't think it should still smell like it's about to burst into flames after all this time. I've finally decided to chuck it after my experience last week. I've really been putting it off and trying to get some of my money's worth since it was expensive, but I don't feel comfortable leaving the house when it's on and I hate coming home to the smell of pot roast and plastic.
