$19.99
Ergonomically designed for extended use
* Designed for hours of use in comfort. The mouse's contoured shape
with soft rubber grips, curved sides and broad palm area provides extra
support for you hand. For left- or right-hand use.
* Compact wireless receiver for easier travel. The tiny Unifying
receiver stays attached to your notebook computer, so there's no need to
unplug it when you move around. And you add other compatible wireless
devices, such as a keyboard or numeric pad, that all use the same receiver.
* Laser tracking for smooth, responsive, accurate cursor control. Works
even on surfaces that often cause problems for optical mice, such as
polished or wood-grain tables.
