Great projector- looks really stylish- easy set up- wireless works great- I use on 130 inch screen- great picture in fairly well lit room ( can read a book in boring bits of movie)- 3D is unbelievable ( better than at movies)- I bought this projector as a replacement for my old DLP projector, wanted something that was 3D capable and that I could move from my dedicated theatre room to other places such as bedroom, so placed on a shelf 6 foot high and lens about 6 metres from screen image just under 130 inch at this distance set at min zoom(smallest picture) also worked on low coffee table about 3.5 metres from screen- have not played with settings yet, but picture is great out of box- lens shift easy to use and invaluable for set up and maintaining maximum clarity and brightness for 3D- although I use my own sound set up for large screen, I tried the built in speakers and was surprised by the quality of sound and feel it will suffice for when I use the projector in other rooms, saving me the trouble of messing around with additional audio equipment- GREAT PRODUCT- VERY SATISFIED
