use it to show picture at a party I be at on the back side of the garage door . then hook it up to a blu-ray player and watch Scott Pilgrim vs. the World . be a great picture . it do need to be DARK in the room you be use it in , due to the 50 lumen . but for the price it do what it say it will . also need to hook it up to external speaker for sound as the internal .5 watt be obviously not enough . overall I highly recommend for those look for a extremely portable projector . if you want videophile quality this be not it , though . but then agian it be not market that way .
