other negative review might possibly be from people who buy a former model , I do not know . all , I can tell you be that this thing be completely awesome . we projector at work fail and I use this and everyone in the room flip out . we be not in total darkness , and the picture -lrb- especially text -rrb- be super crisp . in total darkness , it be obviously even better , beyond word . at home , hook up with a very hard to find hdmus to Mini HDMI cable from a dvd or blueray player yield a absolutely phenomenal and huge picture . everyone i show this to have a jaw-dropping response .
