The fans are too loud. I have these replaced by 90 silent fan from the PC and now the unit is whisper quiet. The image quality is very good compared to the price. The brightness thanks to 100W LED sufficient. Via USB, it will play all formats. Only the built-in speakers are pretty bad. For this purpose, you can cinch connectors other connect. I use a 40 euro 2 * 2m Rolloleinwand and have paid elsewhere 130 Euro for the projector. Home theater at a budget price. Even though my Lcd tv the crisper picture, the big screen makes playing the Xbox and watch ever look much more fun;)
