Very handy 8 1

Surprised by the ease of installation and set up: connect the box to a USB terminal on the other side of the case connect the second screen (bring a vga cable not supplied).
Put the cd, let the program install, very simple configuration and voila.
Works perfectly in office with xp or seven, not tested with games (it's not my thing).
Ideal for tracking including internet tutorials: a screen with the tutorial and on the other screen the app.
Also great for editing photos using software like The Gimp: on a screen tools and on-screen picture but full screen.
Although this practice as usb connection as it is not worth opening the pc (to install an additional card)
Suitable for portable pc: possibility also to display the same on both screens which can be useful during a training example, the instructor uses his mobile and students can take on another much screen great.
Finally that good and affordable.
