this be a great little projector . I use it at home and at my office . the trade-off be size and pixel vs brightness and noise . it be very small and have a descent resolution . to pay for this , you have to sacrifice a bit of brightness and a little fan noise . there be no battery so it always need to be plug in . if you need fall within that realm -- go for it . I really like that I can just leave it on much like I leave on my monitor to display image because of the 30000 hour bulb . one glitch be that the focus change after warm up but then it be good .
