Thank you for viewing my listing. This product is a panel ceramic heater with human sensor and room temperature sensor, released by Three-up. As it is a panel heater, it warms up gradually, so you are less likely to feel that the room becomes dry. Due to shipping costs, I am unable to lower the price any further, but I have reduced it from 4000 yen to 3444 yen yesterday. Please consider it. Regarding scratches and stains: As you can see in the photos, there are some small scratches. There is nothing particularly noticeable on the back. There are scratches on the panel, but the black part of the main unit's operation buttons doesn't have many scratches (photos 6 and 7). The batteries in photo 12 are listed as two, but only one is included as one is in the remote control. Regarding operation, I have confirmed that it works without any problems from both the main unit and the remote control. Therefore, please understand that we cannot accept returns even if you send a message saying that it does not work after the product arrives. Also, I have tried to include all the scratches, but they may look different depending on the lighting. We also cannot accept returns if you send a message saying that there were more scratches than expected after arrival. Therefore, if you would like photos of specific areas, please comment beforehand and I will add them. - Product name: Panel Ceramic Heater - Size: Approximately 48 x 15 x 41cm - Weight: Approximately 3.8kg - Power: Strong 1200W, Weak 600W - Power supply: AC 100V 50/60Hz - Cord length: 1.5m - Accessories: Instruction manual, remote control, spare battery - Functions: Human sensor (automatic operation), Temperature setting (18-30°C), off timer (1h, 2h, 4h) Child lock, activated carbon filter Touch sensor on the operation panel - Human sensor detection range: 60 degrees up and down, 60 degrees left and right (approximately 2m) Panel ceramic heater, panel heater, ceramic heater, foot warmer, work from home, human sensor, room temperature sensor, temperature setting, with timer, touch sensor, with remote control Thank you for viewing.
