Manufacturer description
The seenda Wireless Trackball Mouse keeps your hand planted while your thumb does the work, which is the whole point of a rollerball design: you stop sliding a mouse across a desk and start steering the cursor from one spot. The contoured purple shell follows the curve of your palm and is sized for medium to large hands, so the thumb sits naturally on the ball instead of stretching for it during long sessions. Five DPI steps (200, 400, 800, 1200, and 1600) let you drop to fine sensitivity for design work and jump up for fast document scrolling. Because the sensor reads the ball rather than…

Frequently Asked Questions
Does the seenda trackball work without a mouse pad?
Yes. The sensor reads trackball movement rather than the surface below, so it tracks on a desk, on fabric, or resting on your hand with no pad.
How many devices can it connect to at once?
Up to three, using either the included 2.4G USB receiver or Bluetooth. A mode button on the back of the mouse switches between them in one click, with no driver install.
What DPI settings does it offer?
Five adjustable levels: 200, 400, 800, 1200, and 1600 DPI. The lower steps suit precise design work, the higher ones suit fast document scrolling.
Does it use replaceable batteries?
No. It has a built-in rechargeable battery that charges over the included cable, so you never buy disposable cells for it.
Will it fit small hands?
seenda designs it as a full-size ergonomic shell for medium to large hands, with palm support and steady thumb control. Smaller hands may find the reach to the ball long.
