I buy this as a entry-level projector for my home office , for kind of as a toy\/experiment , and have be please with the result . the picture quality -lrb- 640x480 -rrb- be obviously low-end by today 's hi-def tv standard , but if you goal be to have a big screen at a low price , preferably as you `` secondary '' -lrb- i.e. not as you living room centerpiece -rrb- tv , then this be a good buy . I be use it for dvd , Roku , and computer , project on a $ 50 pull-down screen , and it project a 80 '' image from about 12 foot away . the picture be not too bright , so the room have to be totally dark for best result . the kid love it for the `` movie theater big-screen '' experience , and they do not complain about the video quality . I have use it to watch MLB tv and tv show via Roku , and that be pretty cool - again , we be not talk razor-sharp picture , but definitely good enough for I . I recommend it to any buyer who be ok with adjust his\/her expectation in order to get a inexpensive big-screen `` for fun '' . if you be a buyer who want a top-of-the line high-def video experience , I recommend get a higher resolution tv or projector .
