With a black-and-silver color scheme that fits in with most modern computers, the MX610 left-handed laser mouse is shaped so that your hand rests in an upright, neutral position for better ergonomics. Two volume buttons, a mute button, and the e-mail and IM buttons are lined up on top of the mouse, along the right edge; two programmable buttons are placed further down on the side for easy thumb access. The rubbery scrollwheel moves smoothly, providing tactile clicks but no noise. The wheel also tilts left and right, letting you scroll horizontally. There's a small on/off button on the bottom, and the mouse shuts off automatically when the computer shuts down or sleeps. A battery-indicator light on top of the mouse lets you know when you're running low on power.
