A different kind of comfort. A different kind of control.
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.*
