Summary: Ridiculously noisy on 'Normal' so only way to use it is to accept slightly dimmer image on 'eco'. Also could not get working connection using the USB port. So very disappointed and have returned it.
Summary: This is a really great piece of kit. I bought it because I give presentations to small groups and am fed up with borrowing one. It projects onto any surface and shows a clear picture in a light or dark room! It's light, portable and easy to set up. Have also used it to project photos, videos, DVDs and downloads from lap top onto big screen which are also amazing quality. So as you can see I am really chuffed with this purchase.
