I don't usually write negative reviews. but. Let's start with confusing poorly translated instructions. Add microscopic charts and graphs. Add to this. You have to "turn on" the USB part every time you connect the USB part of the computer to the HDMI part while the HDMI part (with the VERY! short cable) is connected to the big display. Conclusion: absolutely cumbersome, incomprehensible and uncomfortable. The only good thing: Instant refunds upon request and no need to return an unusable device. Next to. not bad.
