the picture quality and quiet operaton of this projector be outstanding . the problem be the pixel have start die out now and I only have 387 hour of view time on this unit which I buy back in January , 2011 . I be go to contact Amazon and Vivitek and see if I can get it replace . I 'll let you know how I make out ... ok , so it be January 21 and still no rma number from Vivitek to return my defective unit to be repair . they have the worst customer service ever ! I explain my dilemma to Amazon and let I tell you , it be the best customer service I have ever encounter ! they understand the problem and send I a new replacement of the exact same model by next day air . and when I have to return the old one they even pay for the shipping . Amazon will definitely get my business in the future . WELL DONE AMAZON !
