it be not the brightest projector but it work well in a dark room . I use this for `` drive in movie night '' on my garage and it work great . it really shine up close though with the image under 55 '' or so . most people probably buy this for business or some practical purpose but I buy it just to use with my tablet for play game or watch movie while camping , etc. . the only downfall I have find be that it be way dimmer when run on battery and it wont last long enough for a full movie . I wish there be a external battery system for it that would allow it to work on full brightness for 3 + hour . if you be look for a tiny projector that can be use anywhere , this be the best I could find and I be very happy I buy it .
