I had this for a few years now. I dont really use it much but when I do, I have to use a liner and one of my pot covers to put on top of the crock pot lid. The lid doesnt really seal right. There are just two settings...high and low. Even with low my crock pot cooks fast. It should be fool proof but since it's always cooking too quick I keep thinking I did something wrong. I got it as a wedding gift and it's pretty small so it cant really feed the whole family. Also since I dont use crock pot often there's really no need for me to buy a bigger one.
