With its secure reliable Bluetooth technology the wireless Mighty Mouse goes wherever you do. Pair it with any Bluetooth-enabled Mac to work untethered and uncluttered at your desk or on the go - it operates with either one or two AA batteries no bulky dock required. The wireless Mighty Mouse features a laser tracking engine that's up to 20 times more sensitive to surface details than traditional optical technology. That means it can track with precision on more surfaces than ever, even smooth or polished surfaces with no mouse pad required.

Perfectly positioned to roll smoothly under just one finger Mighty Mouse's scroll ball offers full 360-degree scrolling capability up/down left/right and diagonally. You can scroll long web pages, pan full-size images, maneuver around large spreadsheets, control a video timeline and more. And you can even click the Scroll Ball to access your favorite Mac OS X features such as Dashboard Spotlight or Expos.

It looks and feels like a sleek one-button mouse but Mighty Mouse's smooth top shell hides a powerful secret: touch-sensitive technology under the shell detects which part of the mouse you're clicking so you can both left-click and right-click. And if you prefer the simplicity of a classic one-button mouse Mighty Mouse is up to the task. - just use the Mac OS X system preference pane to configure it how you want.
