Summary: This product has been a severe disappointment. The first thing I noticed was that the screen is coated with a silver membrane that makes it hard to see even under ideal lighting conditions. Glare was very bad. After connecting it I attempted to load the drivers. The Windows setup program crashed.
Summary: Tried to install the driver for windows7 But neither worked for usb or serial. Useless in some applications. Cursor Pointed to other functions. Can not calibrate in setup. From what they said the touch driver has problems and may include a virus.
