1.- It is not bright enough. Even in a pitch dark room if you are watching a movie Which has dark scenes most of the time, forget about it you will loose your eye sight. I will repeat my self again It Is not bright enough for movies.
If you need to make a presentation or something of sort did then its passable, of course Assuming you are in a dark room.
2.- The fan is loud. You will hear the fan all the time unless you wear headphones or some external speakers blast.
I reccomend if you did do not need the portability buy a non-portable projector for the same price.
