Here's the mouse designed from the ground up for people on the go. Logitech's Cordless Optical Mouse for Notebooks expertly combines an elegant, compact shape with the advanced features that mobile warriors require. With its convenient carrying case, it's easy to pack it up and take it anywhere. When you're ready to use it, just pop the sleek USB receiver into your notebook and start pointing, clicking, and scrolling. Logitech's Fast RF cordless technology delivers all the convenience and freedom of cordless, with no compromise in performance. And because it's optical, you can use it on almost any flat surface and never clean a mouse ball ever again.
