I be look for a inexpensive projector for we church to use on movie night and 2500 luman seem enough to do the job . be a teacher I have use many projector in school as well as at conference some cost many time what I pay for this unit . when this one come in I plug it into my netbook and be amaze at the picture it have . it be not only very bright but the color be amazing . metallic color like silver and gold in the video I watch seem to shine out from the screen like sunlight hit real silver . further the sharpness and clearity of detail on hd video be better than any projector I have ever see when project 12 ' wide . the unit need no install software or anything to start it and the netbook sink up plug and play and they start on they own just by plug it in . I do later install they driver for the projector to try it at higher resolution . I run it for 6 hour straight with no issue to test it as I have read review that suggest it cut out on people and lose signal after a time . I have no idea what problem they be have it work flawlessly connect to my netbook . in short you could not find a better projector that be easier to set up and use for any price !
