الماوس اللاسلكية Logitech Trackball M570 من لوجيتك

Work in comfort with a stable, sculpted trackball that supports your hand and lets you rest your arm.

Logitech® Unifying receiver—the tiny, wireless receiver that stays in your laptop and lets you add compatible devices as you need them.

With up to 18 months of use from a single AA, you might just forget your trackball uses batteries at all.

Your trackball stays in one place, so you don’t have to move your arm to move your cursor. Its sculpted shape supports your hand to let you work all day in comfort.

Short on space? No problem. Because the trackball doesn’t move, it’s perfect for tight workspaces and busy desks.

Millions of people have loved the Logitech Trackman Wheel. We’ve refined its proven shape to create the M570.

You get the reliability of a cord with cordless convenience and freedom—fast data transmission and virtually no delays or dropouts.

Who wants a cord in the way? The robust wireless connection lets you control your laptop, desktop computer or home theater PC from up to 30 feet (10 meters) away.
