We have one and we use it frequently in the fall and winter. But we only use it on weekends or vacation days. DH and I are too nervous to leave it plugged in all day when we are gone (like leaving the coffee pot running). Kind of defeats the purpose, I know.
We have a couple "fix it and forget it" recipe books and use them quite a bit. We mostly do stews, soups, chilis. We haven't had much luck with recipes that call for whole pieces of meat (like chicken breasts) because it tends to get dried out or burnt on the edges. We have a lot more success with "soupy" things that have chopped up meat.
