I ended up not using this after purchase, so it's unopened. Please do not purchase if you claim "there are scratches or stains" or "it doesn't work in my home environment" and demand the same quality and support as a new product. (This is a low-priced, used item sold by an individual, so I will not address any operational issues, including those suspected to be caused by shipping troubles. If you require a performance guarantee, please purchase a new product from a business instead of using Mercari.) Returns are not accepted to prevent changes in condition or swapping after purchase. Price reductions, individual sales, and dedicated pages are not supported.
