It looks great, it works like a dream, and it fits just about any hand like it was made especially for it. It's the Logitech Cordless Click!, the optical mouse that delivers style, substance, and value. Featuring Fast RF cordless technology, it gives you the performance of a corded device but without the cord. So you won't have to deal with tangles and clutter anymore. And because it's optical, you'll actually enjoy working as you glide the Cordless Click! smoothly across almost any flat surface.
