Matrox DualHead2Go Digital ME External Multi-Display Adapter

Got this Matrox DualHead2Go Digital ME adapter still in the box. It lets you hook up two DVI monitors to your laptop or desktop through a Mini DisplayPort or Thunderbolt port. Pretty handy if you need more screen space for work or whatever. Box has a little wear but the unit inside is good to go. Mac compatible too. I upgraded to a MacBook Air and it doesn’t work on it.
