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. Requires Logitech SetPoint software (Windows) or Logitech Control Center software (Mac OS X), available for download at www.logitech.com/downloads. Battery life may vary based on user and computing conditions. The laser sensor does not work on glass or mirrors.
