C:net Mini Ceramic Heater Width: 17 cm x Height: 28 cm Depth: 13 cm Purchased in November 2017 and used for one season, then stored at home without use. Operation has been confirmed. It works without any problems. Filter cleaned. It's very warm for your feet and is perfect for the washroom or toilet. There is no instruction manual. There are sticker marks on the box, but there are no problems with the main unit. Thank you.
