SONY nasne (Sony nasne) HDD 1TB model CECH-ZNR2J I have confirmed the operation of this product before listing. I connected the product to the network and installed the "torne mobile" app on my smartphone. I have confirmed that TV viewing is possible using nasne from the smartphone. There is no significant damage or dirt on the exterior, but there is some wear and tear due to the item being a used product. The items for sale are all shown in the first image. The smartphone used for operation confirmation is not included. Please feel free to ask if you have any questions. Thank you.
