I am a long-time Crock Pot fan. I received my first as a wedding gift 20 years ago. I used that one until last year when it finally quick working. I purchased this one because I thought it would be a better because of the ability to set the time on it. I have tried using it more than 10 times and at least 5 different times I have come home after leaving it on the "high" setting and the food was not done after 10 hours. I left a pot of beans on and continued to cook just trying to see how long it would take, and the next morning they were finally done, after 24 hours of being on the "high" setting. I never had this problem with my old original Crock Pot. With this one you never know if your dinner will be done when you get home, which to me if the purpose of using a Crock Pot!
