So we’ve had this crockpot for nearly a year. We’ve tried cooking with liners, without liners, on warm, low, and high heat settings …  still, no matter what we try we end up with raw, uncooked vegetables and tough, chewy meat.  Other reviews talk about it getting too hot and melting the handles, but we can’t even get it hot enough to cook. I do like that what we’re cooking doesn’t smell up the whole house, but it doesn’t do any good if it doesn’t cook it. Even after 8 hours, the lid and sides of the crockpot are only warm, not too hot to touch.
