I needed a projector for teaching German and did not want to spend too much the first time. Positive: bright image, many connection possibilities, relatively simple operation. Negative: the speakers are unusable. In a space of 14 - 20 People the rear seat passengers listen to little or nothing. Why you have saved just with the speakers, is beyond me. So I need to connect external speakers still, because the laptop speakers are not loud enough. The second negative point: in order to get a reasonably large image that you can also check out 8 or 10 feet away still, you have to be at least 5-6 meters away from the screen. So you need a long power cable and - if you do not sit in the middle of the room, but most of the head, a long HDMI or VGA.Kabel.
All in all. he is not what I expected and I give the device probably back.
