It's the Apple wired mouse that reinvents the wheel — the scroll wheel. This lightly used Mighty Mouse features the amazing Scroll Ball that lets you move anywhere inside a document, literally without lifting a finger. And with touch-sensitive technology concealed under the seamless top shell, you can choose either the versatility of a four-button mouse or the simplicity of a single-button beauty.

Innovative Scroll Ball and button
Perfectly positioned to roll smoothly under just one finger, this used 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 Tiger features such as Dashboard, Spotlight or Exposé.

Touch-sensitive top shell
This Apple wired mouse looks and feels like a sleek one-button mouse, but this used 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.

Force-sensing side buttons
When you give Mighty Mouse a squeeze, force-sensing side buttons can be configured to activate Mac OS X features such as Dashboard, Exposé or a whole host of other customizable features.
