This is a junk item: a Sharp BD-W550 500GB Blu-ray recorder with simultaneous dual recording. It was manufactured in 2013. The reason for the "junk" status is that an alert appears on the screen stating, "The fan on the back of the main unit may not be operating correctly. Please check the fan." While it was usable, there is a possibility of further deterioration, so it is being sold as a no-warranty junk item. Please purchase at your own risk. Regarding basic operations, all functions have not been confirmed due to the lack of a TV connection environment. I have confirmed Blu-ray playback by connecting it directly to a computer display via HDMI. DVD playback has been confirmed. HDD recording and playback have also been confirmed. Various settings can be confirmed. The display is clear and consistent. During operation checks, the pickup lens was cleaned with a Diga wet Blu-ray lens cleaner. Operation with a remote control I have on hand was also confirmed.
