Trackball Performance Upgrade The PERIPRO-303 Trackball series offers the most widely used 34 mm size for trackball mice on the market. All Perixx trackballs are produced in Europe with the highest quality and precision. Advanced coating techniques with two finishing types support a highly sensitive sensor and better performance for all trackball mice.

Glossy and matte surface: Two types of finish surfaces (glossy and matte) for different work modes. The glossy surface provides agile and smooth movements and is specialized for quick navigation across large and multiple screens. The matte finish is specialized for precise pointing and is ideal for document, Excel, and bulk data processing.

Compatible mouse models: Not just a backup replacement, but also the perfect upgrade for various 34 mm (1.33 inch) trackball mice: Perixx: PERIMICE-517/717, Logitech: MX Ergo, M570, wireless, Trackman Wheel (note: Trackman Marble not included), Elecom: M-XT3DRBK (EX-6), M-DT2URBK, Sanwa: MA-WTB43BK.

Trackball cleaning tip: Use either a soft brush or a soft, lint-free cloth (lightly dampened with water) to gently wipe dust off the trackball.

Sensor: The sensor is just as important as the trackball for accurate tracking. Gently wipe visible dust off the sensor with a soft brush.
