LogitechÂ® Wireless Mouse M705 lets you power on... and on. It uses far less power than comparable wireless mice from other companies, so youâ€™ll go up to three full years between battery changes*. And it uses a tiny wireless receiver that stays plugged in to your computer, so your mouse is ready to go â€“ whenever, wherever and for as long as it takes. Plus, hyper-fast scrolling means youâ€™ll fly through long documents to find what you need in a flash. Laser tracking means youâ€™ll get smooth, responsive cursor control. And the sculpted, right-hand shape means youâ€™ll be as comfortable finishing up as you were getting started.
