Overall, it shows signs of use, but it still works without any problems. I am selling it because I bought a new heater. I don't have one now, but I had a dog all last season. I will take the utmost care, but there is a possibility that dog hair may be attached. If you are concerned, please refrain from purchasing. It will be shipped in a recycled box. For those who understand that it is a used item, thank you. Type...Panel Heater
