Better than we thought but ...

On the size I expected not much and was pleasantly surprised!
My purpose was relatively simple: mounted upside down under a shelf to the projector "highlight" in my store certain items.
The brightness of the light source is sufficient for this purpose in current operating perfectly and the minimum distance even well below the indicated 50cm.
The possibility of being able to store data directly on the device or even use a USB stick I find very good and in my test 3 different sticks were easily recognized.
The image quality is very good in the dark and even in a slightly darkened room, it is still inadequate. The supplied cables should for most users absolutely rich, at a pinch, there are also still or USB card reader.

Unfortunately, there are also a few negative points.
* "Premium speakers for excellent sound" Well ... 1W sound stop also like a 1W, but the sound is fine.
* As an additional screen for a PC or notebook, the device is due to the low resolution, unfortunately, almost inappropriate.
* The fan is - as already criticized by others - much too loud. Placed beside the notebook on the table is one annoying pretty quickly. Depending on the speed of the fan, of course, will also change the tone and hardly one has mentally hidden the sound will be characterized again reminded.
* In battery mode, the brightness is automatically reduced (can not be changed). In the dark, the only notice when we look conscious effort. In semi-bright conditions the difference is, unfortunately, quite clearly.
* The battery life of 2 hours to reach only in Eco mode which in turn greatly reduces the brightness.

Overall, of course, everyone has to decide for himself whether he wants to spend nearly EUR 350 for the device, for me the projector is well worth the money!
