What Mouse Does Primmie Use?

Primmie's mouse history

The history covers 18 periods, 17 switches and 8 different models since July 2024. It started with the Logitech G Pro X Superlight Red, used for 1.4 months.

The Razer Viper V3 Pro White is the constant. Across 5 periods it adds up to 13.5 months (1.1 years), and he has returned to it 4 times. It also holds his longest single stretch: January 2026 to August 2026, 6.3 months.

The Viper V3 Pro Faker Edition shows a similar pattern. It has 4 periods, 3 returns and 3.2 months in total.

Several models appear only once. The Lamzu Maya X Black ran for 2.5 months, from September 2025 to November 2025. The Viper V3 Pro Sentinels Edition lasted about 9 days.

The current Viper V4 Pro White is at about 9 days so far, so its place in this history is still open.

Mousepad

Since August 2026 Primmie has used the Pulsar eS Saturn Pro Red, 1.8 months so far. It is a 50 x 50 cm cloth pad, 4 mm thick, with stitched edges.

It is rated as a Control pad, with very low static and very low dynamic friction. The glide difference between the X and Y axes is 6.72%.

Every pad before it was an Artisan. The Hayate Otsu V2 Soft Black ran the longest single stretch, 8.4 months from November 2024 to July 2025. Just before the Saturn Pro he used the Artisan Ninja FX Zero Soft Orange, from April 2026 to August 2026 (4.7 months).

Marvel Rivals uses the same 800 DPI, with 4.50 for both vertical and horizontal sensitivity (eDPI 3600).

The polling rate differs by game: 1000 Hz in VALORANT and 2000 Hz in Marvel Rivals. The Viper V4 Pro supports up to 8000 Hz.
