I buy this projector for my rotary Club . unfortunately , do not test the project in time to send it back in the allotted time frame . the problem with the projector be that the image project be not bright enough . I try work with the manufacturer , even send it back to they for repair and pay $ 75 to have it check out . when the projector be return there be no improvement in the brightness . the manufacturer still insist that be the best they could do . we club eventually buy another projector , the brightness do not compare . the projector sit collect dust . I want every Rotarian in the world to know this .
