Summary: By T. Ko (Euless, TX) (REAL NAME) I brought this project through AMAZON. No doubt it is a good projector - very small and have sharp picture. But, when the fan kicks into high gear, it is unbearable. People is unable to hear my voice during the presentation. Therefore I return the projector. Unfortunately I have to pay 15% restocking fee. It will be a good product if Optoma can make some minor change in this respect.
