Summary: The projector works fine if the room you are in is completely dark, even though some of the text is hard to read, but that is to be expected with the resolution it provides. If you are looking for something for your kids to play with it ill do the job just fine, but not if you need to use the disply for presentation purposes. The projector just doesn't put out enough light to do a good job in a lighted room even if the room is dimmed.
Summary: I ordered this and the 3M MPro 120 to compare them, and for me the MPro was the better choice. The menu select wheel on the Optoma seems to be very tempermental (hard to select what you want) and in a bad location relative to where the unit connects to the computer. I had this connected to my MacBook and I had to manually change the display resolution to get the projector to work.
