Logitech G5 Laser Mouse review: Logitech G5 Laser Mouse

The rest of the buttons reflect what we've come to expect from a modern mouse. You get a scrollwheel, two main buttons, and one thumb button. The scrollwheel incorporates Logitech's Tilt Wheel technology for side-to-side scrolling, but we don't think it's an adequate replacement for the dual thumb buttons found on the MX518 and other mice. You can't move your middle finger from the right side of the wheel to the left without moving your index finger off the left mouse button. That's not a problem when you're working with a spreadsheet, but for gamers who map the left button to fire their weapon, such finger gymnastics may lead to a potentially dangerous loss of weapon control. We'd prefer an extra button to hit without having to shift your finger position.

The Logitech G5 Laser Mouse offers a 500MHz USB polling rate and processes 6.4 million pixels per second, which lets it process plenty of clicks per second. The sensor can also track movement at a rate of 45 and 65 inches per second, depending on your mousing surface. For optimal performance, use a dark-colored semireflective surface with an irregular texture. The laser sensor will work on pretty much anything except a mirror, though.

Logitech offers a three-year limited warranty on hardware, where most mice manufacturers stop at one. The company's support Web site includes an extensive troubleshooting database, and phone support is available Monday through Friday from 6 a.m. to 6 p.m. PT.
