Manufacturer description

The Kensington Orbit Mouse trades the standard mouse footprint for a 40 mm blue trackball you steer with your thumb and fingers, so your wrist stays planted instead of sweeping across a desk. The award-winning Scroll Ring circles the ball: spin it to glide through long documents and web pages without repeatedly clicking a wheel. Optical tracking keeps the cursor precise across the screen with less hand movement, and the hard, perfectly spherical ball surface gives you fine control for detail work. Kensington built the Orbit to be ambidextrous, so left- and right-handed users get the same…

Frequently Asked Questions

Is the Kensington Orbit good for left-handed users?

Yes. The Orbit uses an ambidextrous design with the ball centered and the two buttons mirrored, so it works equally well for left- and right-handed users with no separate model needed.

How does the Scroll Ring work?

The Scroll Ring is a dial that circles the 40 mm ball. You spin it with a finger to move up and down web pages or documents continuously, instead of clicking a traditional scroll wheel.

Does it need batteries or a wireless dongle?

No. This is the wired USB version (K72337EU), so it draws power over the cable. There are no batteries to replace and no receiver to plug in or misplace.

Can I reprogram the buttons?

Yes. Kensington's free downloadable KensingtonWorks software lets you assign program functions to each of the 2 buttons and adjust cursor and scrolling speeds.

Does it work with Mac as well as Windows?

Yes, Kensington lists it as PC and Mac compatible, citing Windows Vista and Mac OS X. Check the product listing for current OS support before buying for a newer system.
