I have have this projector for four week and it work like a champ . the noise level be average , but everything else about the projector be top notch . my image be 129 '' diagonal and the 1080p\/1080i image be crystal clear . if ceiling mount be sure to have the projector properly center as it do not come with lens shift . compare to other projector in this price range it be hard to beat with the number of lumen , lamp life , and the length of the warranty .
