(Old model, but barely used, in excellent condition) ROOMMATE Far-infrared Panel Heater EB-RM5400A Made in 2017 Power-on Operation Checked. Found during a cleanup of a warehouse in the countryside. According to my grandfather, he bought it urgently for a festival and only used it for about 3 days each in 2018 and 2023. I think it's in very clean condition with no noticeable scratches or stains (personal opinion). Please consider purchasing if you understand the product. Please refrain from purchasing if you are overly concerned about details.
