Logitech MX1000 Laser Cordless Mouse Review
 

When I first heard of the MX1000 Laser my first thought was "I wonder if I could use it as a laser pointer?" The answer is no. All lasers conform to one of four classes, depending on usage and power. The MX1000 is a Class 1 laser device - extremely low-powered and can be stared directly into, even with a magnifying glass, for extended periods without causing any eye damage.
