4K tuner, model 4S-C00AS1, with remote control. After installation, I realized it was different from what I intended to buy, so I removed it immediately. There is a small scratch on the surface of the main unit, but it was only connected for about 10 minutes. Since I am not familiar with electronics, please check if it is compatible with your equipment before purchasing. I disposed of the box when I opened it, so I will pack it with bubble wrap, etc., before shipping.
