Summary: I paid $800 on a projector that worked about 5 or 6 times. After that, it had vertical lines and no picture. The packaging is still on the projector, but we were in Asia and did not return until after the warranty. I called Optoma and spoke to the manager. My frustration is paying so much money for a defective projector. I would think they company would care about their reputation and customer enough to do something.
