I received this as a gift, but I already have one, so I'm selling it. The box has been opened, but the contents are all unopened. Therefore, I haven't checked the operation, so please refrain from returns for initial defects. As for the accessories in the third photo, I use the same ones myself, but I have unused, brand-new accessories that I'll include as a bonus!
