Overview
Rolling the central ball moves the cursor, and a patented scroll ring around it scrolls pages up and down. The body stays put on the desk while the ball does the work, and a detachable wrist rest comes with it.
Dual wireless connection and four cursor speeds make it easy to switch between a desktop and a laptop. Only two buttons are listed, so heavy shortcut users may want more, and the listing gives no operating system versions.
Who it's for
Left-handed and right-handed users who want to move the cursor without moving the arm, on a crowded desk or with sore wrists. Buyers who need extra programmable buttons should choose a model with more of them.
Pros and cons
- Works for left or right hand
- Two wireless modes in one device
- Adjustable cursor speed
- Detachable wrist rest included
- Only two buttons listed
- Rated for PC platform in specs
- Operating system versions not listed
Performance notes
An optical sensor tracks the ball, and the DPI setting changes how far the cursor travels for each roll. The scroll ring turns the page without lifting the hand from the ball. The receiver link and the Bluetooth link are both encrypted, and battery life is not given in the listing.

Frequently asked questions
Does the Kensington Orbit Wireless work with a Mac?
The description says it is plug and play for Mac or PC. The spec table lists the PC platform and gives no operating system versions, so check your version with Kensington.
How does the Orbit Wireless connect?
It offers a USB receiver and Bluetooth, both protected by the encryption named in the description. The USB receiver is listed in the box.
Is the Kensington Orbit a thumb trackball?
No. The ball is in the center with a scroll ring around it, and the design is ambidextrous rather than built for one hand.
