Turn your regular monitor into a touch screen display with this AirBar sensor. It connects easily to a standard USB port for quick use, and it works without draining the battery. This AirBar sensor works with most 15.6-inch monitors, and the touch field supports almost any object for precision and accuracy.
Attach the airbar, plug into USB port, and instant touch screen! Surprisingly accurate. Had it a few weeks now and love it. My husband will buy one for his 17" gaming laptop if/when they make that size.
