small, compact, ingenious

I need a small, mobile deployable projector for training presentations. This equipment has thrilled me. I berteibe the projector on a netbook; both through HDMI, and VGA on the device can be quickly and reliably connect. The image is very sharp even in daylight or only lightly darkened room. All pictures / texts / presentations are very readable. I use a small portable screen (ca. 107x76 cm); the distance from the device to the screen is approximately 1m in the presentations. If a greater distance, the room should be dark, in order to obtain a very good resolution. But the Bildschäfe is just amazingly good even at lower darkening. The unit is fairly quiet and easy to use. The focus adjustment is also good. I'm very satisfied; the projector is much better than expected - especially for this low price.
