Mine mostly sits because I find the instructions and UX inscrutable. I've made some great ribs, but just as often something goes wrong and the device doesn't warm up enough, or doesn't form a seal and cooks off the liquid or burns the meat.

You don't get any indication that things are going right until the timer starts going down, but that's many minutes after you start it. It also comes with two completely incompatible rice recipes, one of which doesn't use rice mode, and no explanation of why. Just terrible UX.
