I purchased this from Mercari in 2023 and tried it once with my cat, but she wouldn't go in, so I've kept it in storage. The light in the center of the top (red arrow in the second photo) no longer lights up, and I've only wiped it down with alcohol, so I'm selling it at a reduced price. Regarding scratches, there are fine scratches on the LCD screen (where the temperature is set) and small scratches on the side. There may be other overlooked imperfections, so please refrain from purchasing if you are sensitive to such details. Please check the photos. Operation has been confirmed. The original box, instruction manual, and a new filter are included. I will ship it in the original box, wrapped in bubble wrap. Regarding usage, I don't know how much the previous owner used it, but I've only used it about 3 times to check the operation, and my long-haired cat used it once. Since it's a large item, I plan to ship it on Wednesdays or Thursdays when I have help. Depending on when you purchase it, it may take some time, so please ask if you have any questions. Please consider purchasing it.
