Logitech - M570 Wireless Trackball Mouse - Gray/Blue

Trackball mouse with reliable optical tracking
Trackball mice require less wrist movement than traditional mice, since they track the motion of the built-in ball instead of the movement of the entire mouse.

Wireless connection
Wirelessly connects to the included Logitech Unifying receiver, which plugs in to your computer’s USB port.

4-button design
Features a scroll wheel and back and forward buttons, so you can easily control computer functions.

Sculpted shape supports your hand
Allowing you to remain comfortable for long stretches of time.

Compatible with most Windows and Mac computers
Works across a wide array of computers.

In 4 1. Lazy paid $5.99 for same day delivery. Who does Best Buy think they are Amazon? I’m betting against same day delivery.

Not the best for reliability (the buttons wear out in time) but otherwise these things are vastly superior to an ordinary mouse for most purposes.
