Quality OK, but disappointing due to excessive noise
18 February 2012
Summary: I purchased this in October 2011, shortly after the product was available online (bought from AVPartsMaster). Unfortunately, the projector suffers from being noisy. There is an intermittent noise that is evident when there is a lot of colour on screen. You cannot watch movies without being aware of this annoying buzzing. This projector has been returned two times to Optoma for repair.
