Perixx Perimice-517 Wired Trackball Mouse 34mm 7 Button

Right-Handed Ergonomic Trackball

The Perixx Perimice-517 is a wired trackball mouse built for right-handed users who spend long hours at a computer. A 34 mm trackball sits under the thumb so the cursor moves without shifting the whole arm. Seven programmable buttons include left, right, forward, backward and two DPI switches. A laser sensor delivers three fixed resolutions of 400, 1000 and 1600 dpi. Silent clicks reduce noise in shared spaces. The sculpted shape supports the palm and wrist to help lower strain during extended sessions.

Suits Desk-Bound Users With Limited Space

Office workers, gamers and anyone managing repetitive strain injuries benefit from the stationary design that keeps the forearm still. The compact footprint of 130 x 107 x 45 mm fits tight desks and eliminates the need for a mouse pad. Buyers who prefer a traditional sliding mouse or need left-handed ergonomics should look elsewhere. The fixed DPI steps and lack of software customisation also limit appeal for users who want per-game sensitivity profiles or macro programming.

34 mm Thumb Trackball With Three Fixed DPI Steps

The 34 mm ball diameter and laser sensor combine to give precise control across 400, 1000 and 1600 dpi settings changed by dedicated buttons. This specification decides whether the device matches a workflow that values stationary operation and discrete speed tiers over free-gliding movement or on-the-fly sensitivity adjustment.
