SK-3DWP Power Stabilizer 3DWPro Made by SKNET Model Number: SK-3DWP Included: Main unit / AC adapter / User's guide This is a picture quality adjuster for video equipment. It is a used item. I haven't used it for a while, but it worked normally. I have confirmed that it powers on. The warranty period has expired, so I cannot guarantee future operation. The protective film from when it was purchased is still attached to the label on the top and the connection ports. There are several scratches on the back. Please check the images and consider purchasing with the understanding that this is a used product.
