Has quality gone downhill in 25 years? My Rival crockpot with the lift-out stoneware crock is still going strong. It has somehow survived for almost 25 years! The crock has lots of scratches and scrapes, but no cracks. I use it once or twice a week for at least eight months a year. I thought the plastic lid would have been destroyed by now, but it's also held up well. I run both through the dishwasher, too.
Wonder why yours crack so often? Do you let it cool before you wash it? If it's too hot and you put cold water inside, that might cause it to crack.
I have crockpot envy - I want a fancier one. This one has two temperature settings: boil and warm. A "medium" setting would be nice. An on/off timer would be great, too.
Good luck in your search!
