Review on TeamGee Portable Monitor Display Extender 12", Built In Speakers, Lightweight by Melvin Albarado

They will send you enough cable options to connect monitors to your laptops. I would recommend buying a docking station to power the 3rd screen. The dock only needs to charge your computer so it can power your 3rd screen. The transition from screen to screen is smooth, the volume is sufficient. Ideal for traveling, even with a travel case to protect your screens. A bit heavier than I'd like, but the weight probably makes it a solid and reliable screen.
