Mine's a 2.5 quart, all white (Pegg, I'll bet we have the same model) and I LOVE it. It cooks evenly and not too hot - no cracks either, thank goodness! I noticed in reading the instruction booklet that they advised against sudden temperature changes, eg. not putting real cold ingredients in the crock and then turning it on, not putting a hot crock into cold water, etc., so I've been trying to be careful about that. I agree, sounds like you got a lemon! :(
