Logitech 910-001822 M510 Wireless Mouse, 2.4 GHz with USB Unifying Receiver, 1000 DPI Laser-Grade Tracking, 7-Buttons, Black

The full-size Logitech® Wireless Mouse M510 gives you more control, so you can do more with your mouse. The contoured shape with soft rubber grips gives you the support you need for all-day comfort. You can do more, faster: three standard buttons, Back/Forward buttons, and side-to-side scrolling plus zoom make it a breeze, especially for right-handers. Two years of battery life practically eliminates the need to change batteries, while the tiny Logitech® Unifying receiver stays in your laptop, so you're less likely to lose it. And laser tracking means you'll enjoy smooth, responsive cursor control on just about any surface.
