The full-size LogitechÂ® 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 LogitechÂ® Unifying receiver stays in your laptop, so youâ€™re less likely to lose it. And laser tracking means youâ€™ll enjoy smooth, responsive cursor control on just about any surface. The laser sensor does not work on glass or mirrors.
