I bought the device for use in presentations. For this purpose it is very good. The image quality is very good, the brightness even in daylight too. Setting, assembly, ... everything was perfect and for a great price. The only drawback, and a star deduction from my perspective the volume. We have now but also used the beamer times at home for home theater. In this application, then it points out that the fan noise is quite loud. I can not judge whether it's better in others and if that does not matter at an appropriate sound. Since we (psst .. the kids are asleep ...) at home rather quiet television, that's the sound in any case a limitation. Otherwise, as it is written very satisfied!
