This is our 2nd one in about a year. Makes the best popcorn. We use a cooking grade (high heat) olive oil and Redenbacher white popping corn, then add some Morton sea salt after done. Instructions say dishwasher safe, but cover cracked in dishwasher after about 6 months of heavy use during covid. I glued it several times but it kept cracking in different locations. A complete new unit was about 2x cost of a cover so just purchased a whole new unit and are saving the other new parts. With the new one, we are hand washing the cover and still putting other parts in dishwasher. So far so good. Still the best popcorn we've ever made at home.
