Finalmouse UltralightX (ULX) Frostlord,33g Carbon Fiber Wireless Gaming Mouse 8000Hz Polling, PixArt Sensor, 319 s Click Latency, Huano Blueshell Switches, Medium | M85001M-FL.5CF0604

The Finalmouse UltralightX Frostlord Medium represents the absolute peak of competitive mouse engineering. Created as the final ULX release, this limited-edition model embodies ten years of relentless innovation in physics, materials science, wireless RF architecture, and firmware design. At only 33 grams, ULX Frostlord redefines what is physically possible in esports performance.

 

Key Features

Ultra-lightweight 33g carbon fiber composite chassis

True 8000Hz wireless polling rate

319μs average click latency and 444μs motion latency

0ms debounce delay with intelligent post-press filtering

Limited-edition Frostlord artwork with UV matte competition coating

Driverless XPANEL web-based configuration

 

Performance & Technology

ULX Frostlord leverages a proprietary wireless stack with adaptive RF channel hopping and precision packet scheduling to maintain flawless performance even in RF-dense tournament environments. Dual-MCU architecture separates RF processing from USB transmission, ensuring deterministic packet timing and zero wireless instability at all polling rates.

Custom firmware, developed entirely in-house, passes 83 validation tests before release and eliminates artificial delays common in conventional gaming mice. The result is instant, consistent response where every microsecond matters.

 

Design & Ergonomics

The Frostlord chassis is constructed from a proprietary carbon fiber composite that is three times stronger than ABS and significantly lighter than magnesium. Solid sidewalls enhance grip consistency without adding weight, while the hand-drawn Frostlord artwork is applied using an advanced undercoat process for durability and visual depth. The Medium size is precision-tuned for balanced control across claw and fingertip grips.

 

Materials Engineering

3× stronger than ABS

~33% stronger than magnesium

30% less dense than magnesium

0.8mm wall thickness with full structural integrity

 

Firmware, Sensor & Control

ULX Frostlord uses a custom-optimized PixArt PAW3395 sensor paired with Finalmouse firmware that corrects undocumented chip-level behavior for error-free tracking. Smart debouncing, slam-click protection, lift-off detection, and Tournament Scroll filtering ensure flawless input reliability under competitive conditions.

 

Battery & Efficiency

Despite its extreme performance profile, ULX Frostlord delivers up to 2 months of battery life with intermittent use, thanks to deep firmware-level power optimization that minimizes draw without compromising responsiveness.

 

Why This Product Stands Out

ULX Frostlord is not built to compete on spec sheets. It is engineered to win at the highest levels of play, combining physics-driven advantages, elite firmware, and uncompromising materials. As the final ULX release, it is both a performance benchmark and a collector-grade esports icon.
