Interfacing to your computer through a USB connector, the trackball can be further customized with your choice of resolution: 400, 800, or 1,600 dpi. The LED lights only turn on when the ball is moved and automatically turn off after five minutes of inactivity. Perfect for a first person shooter, an involved day on InDesign, or simply surfing through the vast series of tubes we call the Internet, the CST LaserTRAC Glow Trackball is an ideal deskmate whether you’re busy at work or kicking back at home.
