Other than some dust in spots I can’t really get to, it looks new, and also functions just as good as my modern microwave. I took a video of it heating up a cup of water from 68 degrees Fahrenheit to 140 degrees Fahrenheit in one minute. I can send the video upon request since I can’t post it here. I do not have the temperature probe unfortunately, but all the nobs, buttons, and latches function better than I expected for a 42 year old microwave.
