I asked for a "big simple (not digital) crock pot" last Christmas and received a Rival Crock Pot , seven quart, that just has a knob to select low, high, or warm temperatures. It is exactly what I wanted. I keep three slow cookers - small, medium, and large. I use the large one primarily for large chickens and roast. My previous large crock pot was digital. I am somewhat anti-digital - I don't really trust them. Well, I was right not to - it didn't last very long (one of the temperature settings went out altogether and the other became unreliable) and when the electricity goes off (which it does in our rural area often), it would turn off and not come back on. So I wanted a big crock pot with a manual knob. It works great and even comes back on when the power is restored. The only negative thing about it is that it cooks very hot, by which I mean I have to cut way down on the cook times suggested in recipes. That's okay once you adapt to it and figure out how long stuff needs to be cooked, but not so great at first as everything gets overcooked. Time to Heat Are any slow cookers quick to heat? Cooking Performance Does fine once adapted to how hot it cooks. Ease of Cleaning I use slow cooker liners, which is a complete game-changer. No mess. Ease of Use Couldn't ask for a simpler operating system - low, high, or warm. Design Like any other simple crock pot. That locking lid device that some have for transporting without spills would be nice, but for home this one is fine. Durability I have a very old Rival Crock Pot that is chugging along just fine, so I expect this one to do the same.
