fantastic with small defects

I own some projectors in both the high-end class and in Lowbudgetbereich due my job at the school.
Präsentaionen for this projector to use excellent in slightly darkened rooms, the device is recognized immediately and work at USB 2. 3 The contrast is very good for the size, but not to be compared with a "real" beamer. The connectivity is limited to USB, that should be enough in 90% of cases, since the projector is meant to be used in the teaching area for smaller groups and for presentations, movies can be seen very well, but as I said a home theater does not replace the thing, for smaller Zockabende and Youtube videos, it goes very well, the resolution is completely sufficient and sharp the image is.
The background noise is pleasantly quiet.
The build quality is good, there is not a high end device, which you should always keep in mind. A cheap bisl the thing already looks and the surface is very scratch-prone!
