Excellent "home cinema" projector. It is not a presentation or a pico projector, nor is it marketed as such. It's a shame to see clowns like the guy above giving a two star review because he failed to research his purchase. This type of PJ is not designed to have internal speakers. Pair it with a good receiver and it will shine.
I 100% recommend this Optoma to anyone with half a brain who realises that it is a 'part' of a home cinema setup, not a standalone projector for business use.
