I've been looking for a long time for a way to connect a display, TV or projector via USB and this thing delivers. I was a little worried that this wouldn't work on my old 2009 Macbook Air, but it actually worked. Once you've pulled out HDMI, you should be able to easily find another cheaper DVI, VGA, or Displayport adapter. In general there are no complaints. I would absolutely recommend this.
