The Viper V4 Pro is unveiled as a high-performance gaming mouse featuring Razer HyperSpeed Wireless Gen-2 with ultra-fast 0.204 ms clicks and an 8,000 Hz polling rate, paired with a Focus Pro Gen-3 50K optical sensor for up to 50,000 DPI and Gen-4 optical switches rated for 100 million clicks, all in a lightweight 49–50 g body.

Pricing is set at $159.99, with the Gigantus V2 Pro Large gaming mouse mat priced around $49.99, and availability is immediate.

Razer also announces the Gigantus V2 Pro mat in five versions tailored to different play styles, emphasizing edge durability and travel-friendly, warp-resistant design.

Software support stands out, with in-browser Synapse Web complementing the desktop Synapse for easier on-the-fly configuration.

The editor promises further hands-on updates as more testing is completed.

The mouse’s click mechanisms and scroll wheel are described as sharp yet with a less bouncy click and softer scroll, while the bottom DPI/power button is noted as inconvenient for on-the-fly DPI changes.

Battery life is optimized by Synapse to auto-adjust polling rates when not gaming, preserving power without sacrificing on-demand performance.

Review notes acknowledge that the mouse and mat were provided for testing, with performance strengths across clicks, swipes, and scrolls.</status>
