I purchased this for a home theater, but I've only used it a few times. I heard that projectors are useful for events, so I'm listing it. I checked the operation and found no problems. It has knobs and the height is adjustable (see photos 12 and 13). The included accessory is the power cord. There is no remote control. This is a rare item from Sanyo Electric, which is no longer in business. I don't see any noticeable stains, but it's used, so please refrain from purchasing if you are concerned. I have also listed various other items. Bulk purchases are welcome, so please take a look. I am also listing the DVD player that I was using with this. Price negotiations are possible, so please feel free to consult. Thank you for looking.
