Click more. Scroll more. Do more. Logitech Marathon Mouse M705 uses far less power than comparable wireless mice from other companies. That means you can go up to three full years between battery changes.

Features:

• Hyper-fast scrolling lets you fly through long documents and Web pages with a single spin of a nearly frictionless metal scroll wheel.
• The sculpted, right-hand shape guides your hand to a naturally comfortable position and places customizable control within your reach. Two thumb buttons lets you move quickly between Web pages.
• The tiny Logitech Unifying receiver stays in your laptop. There's no need to unplug it when you move around, so there's less worry of it being broken or lost. And you can easily add compatible wireless mice and keyboards to the same wireless receiver.
• Laser grade tracking delivers smooth, responsive, precise cursor control on surfaces that cause problems for standard optical mice, such as polished or wood-grain tables.
• NOTE: Receiver is present in the battery compartment
