What the 35 meant but I wonder how energy efficient it is after 35 years. Not that I’d get rid of it, if it’s still working. It seems most appliances made to day are lucky not to be in a landfill w/I 15 years. They may have newer bells & whistles which are nice but at some point I wish manufacturers would stop adding new features for a basic appliance & focus on making a simple functional appliance that forever while staying efficient. That would seem like a healthy, earth friendly, green planet thing to do that we could all get behind.
