Finalmouse UltralightX Competition Review: The Lightest and Fastest Wireless Gaming Mouse Yet (2025)

The Finalmouse UltralightX Competition, also known as the ULX, is a product of over a decade of engineering refinement. It redefines what is possible in competitive gaming performance, offering a wireless experience so fast and lightweight that it challenges the limits of physical design. With its carbon fiber composite shell, high-speed wireless tech, and precision switches, the ULX Competition might be the most advanced gaming mouse ever released in 2025.

Design and Build Quality: Featherweight Engineering

At only 33 grams, the Finalmouse UltralightX Competition weighs less than a single strawberry. This ultralight design is made possible by its carbon fiber composite chassis, which combines aerospace-grade durability with extreme weight reduction. Compared to ABS plastic or magnesium, the ULX’s carbon composite offers over three times better strength-to-weight ratio.

Despite its lightness, the chassis feels solid and rigid, designed to withstand intense gaming sessions without flex or fatigue. The solid-sided design introduces improved structural integrity for professional players who demand consistent control under pressure. Its limited edition Raw Carbon finish showcases the natural texture of the material, enhanced by a UV matte clear coat that provides both grip and durability while revealing every fiber pattern and tool mark beneath the surface.

Performance and Technology

Performance has always defined Finalmouse, and the ULX Competition continues this legacy with unmatched precision and responsiveness. It utilizes a cutting-edge 8000Hz wireless system capable of 344 microsecond click latency and 444 microsecond motion latency. This translates to near-instant input recognition that outpaces nearly every other wireless gaming mouse on the market.

In real-world gameplay, this responsiveness provides smoother aim tracking, reduced input delay, and more consistent movement accuracy. Every click and flick feels effortless, allowing competitive players to perform at their highest level without being limited by hardware.

Materials and Craftsmanship

The ULX Competition’s carbon composite chassis is more than just a visual statement; it’s an engineering innovation. Each mouse begins its life in the United States as strands of raw carbon fiber, which are then processed and molded into a lightweight yet durable main cage. The design maintains a perfect balance between strength, rigidity, and minimal mass, resulting in a mouse that feels weightless yet premium in hand.

The UV matte coating used in the Raw Carbon edition enhances the natural feel of the material while improving grip and durability. Finalmouse’s approach to showcasing the raw composite emphasizes craftsmanship, turning each ULX into a functional piece of design art.

Switches and Internal Components

Inside, the ULX Competition uses custom-spec Huano Blueshell switches, carefully selected and binned for consistency and longevity. These switches deliver crisp, tactile feedback that competitive gamers rely on for precise timing and quick reaction shots. The addition of a TTC Gold Dustproof encoder ensures reliable scroll performance with minimal wear, maintaining accuracy even after prolonged use.

This attention to internal detail reinforces Finalmouse’s commitment to producing professional-grade peripherals that can handle the demands of high-level competition.

Ergonomics and Size Options

Recognizing that every gamer has a unique grip style and hand size, Finalmouse offers the UltralightX Competition in three different sizes: Small, Medium, and Classic. This ensures a personalized fit regardless of play style, whether you prefer fingertip, claw, or palm grip. Each model is balanced to maintain the same ultra-low weight without compromising control or comfort.
