This is an HDD recorder with 500GB of storage. All accessories are included, including the original box. I received it in a beautiful condition with almost no signs of use, but I'm selling it because I have no opportunity to use it. I haven't checked the data inside, so there's a possibility that the previous owner's data remains. Please erase it before use. It's sold on Amazon for 27,000 yen.
