Summary: The portability is great and it is light weight and folds flat. Easy to fit in your travel bag. The fact that you only need the USB cable and not a separate power cable is great. But, when the display is being powered from USB (even the dual USB) the display is pretty dim. It is useable, but certainly not as bright as I am used to. I am a Mac user. For Mac you have to download a driver from displaylink.org for it to work.
