Wasserstein Perimice-517 Wired Trackball Mouse 34mm 7-Button USB 1.8m Cable

Right-handed trackball for long sessions

The Wasserstein Perimice-517 is a wired trackball mouse built for right-handed users who spend long hours at a computer. A 34 mm trackball and seven programmable buttons put cursor control and navigation under the thumb and fingers, reducing arm movement. Laser tracking offers selectable resolution at 400, 1000, 1600 and 2000 DPI. Silent clicks keep noise low in shared spaces.

Suited to RSI sufferers, not left-handers

Office workers, gamers and anyone managing repetitive strain injury benefit from the stationary design that keeps the wrist and palm supported. The sculpted shape encourages a neutral posture during extended use. Left-handed users cannot operate the trackball comfortably because the ball and button layout are fixed for the right hand. Buyers who prefer a conventional mouse that slides across the desk should look elsewhere.

34 mm trackball decides fit

The 34 mm ball diameter determines how much thumb travel is needed for full-screen navigation and how the device feels under the hand. A larger ball would reduce rotation for the same cursor distance, while a smaller one would demand finer motor control. If the 34 mm size matches your preference, the seven buttons and four DPI steps cover most productivity and gaming workflows.
