Finalmouse UltralightX (ULX) Frostlord,33g Carbon Fiber Wireless Gaming Mouse 8000Hz Polling, PixArt Sensor, 319 s Click Latency, Huano Blueshell Switches, Large (Classic ) | M89001L-FL.5CN1030

The Finalmouse UltralightX Frostlord Classic (Large) represents the pinnacle of esports mouse engineering. As the last ULX ever produced, this limited-edition release marks the culmination of ten years of uncompromising research across physics, firmware, wireless architecture, and materials science. Built for competitive players who demand absolute performance, ULX Frostlord sets a benchmark no other wireless gaming mouse has reached.

Key Features

Ultra-light 33g carbon fiber composite chassis

True 8000Hz wireless polling rate for extreme responsiveness

319μs average click latency and 444μs motion latency

0ms debounce delay with intelligent post-press filtering

Exclusive Frostlord white-on-white artwork with UV matte competition coating

XPANEL driverless configuration with onboard memory

Performance & Competitive Advantage

At only 33 grams, ULX Frostlord Classic leverages physics itself as a competitive advantage. Reduced mass enables faster acceleration, lower fatigue, and improved consistency over long sessions. In controlled modeling, ULX reaches targets significantly faster than heavier mice, delivering physical latency reductions that exceed common network ping differences.

This advantage is not theoretical. It is felt in every flick, micro-adjustment, and tracking scenario where milliseconds decide outcomes.

Carbon Fiber Composite Chassis

The ULX Frostlord chassis is built from a proprietary carbon fiber composite engineered for unmatched strength-to-weight performance:

3× stronger than ABS

~33% stronger than magnesium

30% less dense than magnesium

0.8mm wall thickness with full structural integrity

Solid sidewalls are integrated directly into the main cage without adding weight, providing consistent grip and eliminating tactile distractions during high-pressure gameplay.

Sensor & Tracking Accuracy

Powered by a custom-optimized PixArt PAW3395 sensor, ULX Frostlord delivers error-free tracking with faster readout intervals and on-chip motion synchronization. Finalmouse collaborates directly with the sensor manufacturer to correct undocumented behavior, ensuring consistency that commodity implementations cannot match.

Tournament Scroll & XPANEL

ULX introduces Tournament Scroll, filtering phantom scroll inputs caused by mechanical edge cases while preserving precise bunny-hop timing. Configuration is handled via XPANEL, a browser-based, no-download utility that stores all settings in onboard memory, making the mouse fully tournament-ready on any system.

Battery & Efficiency

Despite extreme performance demands, ULX Frostlord achieves up to 2 months of battery life with intermittent use. Firmware-level power optimization ensures efficiency without compromising polling rate or responsiveness.

Classic (Large) Shape – Designed for Control

The Classic (Large) size is engineered for players who prefer a fuller, more stable grip. Each ULX size is designed independently, maintaining identical structural integrity while optimizing geometry and mass distribution. The iconic Finalmouse shape, originally sculpted by hand and refined through CAD, remains unmatched in ergonomic harmony.

Why ULX Frostlord Stands Alone

ULX Frostlord Classic is not built to win a spec-sheet comparison. It is engineered to win matches. Every microsecond, every gram, and every line of firmware is optimized for competitive performance. As the final ULX ever made, it is both a technological milestone and a collector-grade esports icon.
