A very useable product at a low price. I use it with my computer, dvd player and after buying an adapter, with my ipod touch (does not come with a ipod adapter). The picture is dark but still good enough to see in a dark room. My biggest complaint is the volume. If you load a movie on the projector the internal speaker is very low. I can only hear it if I am up close. There is no external speaker connection so you are stuck with what you get. I put the movie on the ipod and use an external speaker with that. Although that kind of defeates the purpose of having a internal 4 gig memory. It is a fun toy.
