Reduce strain and work comfortably

The Sferia Wireless Trackball mouse will change the way you control your PC and laptop. By moving around the trackball with your thumb instead of moving around the complete mouse, you will enjoy reduced strain on your wrist, arm and shoulder. Thanks to its ergonomic design, you can work comfortably for hours.

Laser treatment

The Sferia comes with an accurate trackball with a sensitive laser sensor. In this way, your thumb’s movement is perfectly translated to cursor movement on the screen without moving your whole hand. The comfortable thumb rest and ergonomic shape make sure you have a perfect grip on your work.

Control & scroll

The software allows you to alter the 2 programmable thumb buttons so the mouse is perfectly adjusted to your preferences. With the tilting scroll wheel, you can scroll both horizontally as well as vertically which is handy when you are viewing wide documents like a spreadsheet!

Work wirelessly

Want to use the Trust Sferia? Turn it on with the on/off button and plug the micro USB receiver into a USB port. The receiver allows the mouse to work wirelessly within a range of 8 meters. When you are finished using it you can easily store the receiver in the product or simply leave the receiver in your laptop/pc.

In a tight spot

Since you don’t have to move the Sferia when using it, this mouse is ideal for tight workspaces and crowded desks. You can surround yourself with all the documents and charts you need to get your work done, without needing extra space for your mouse.
