Finalmouse UltralightX (Wireless/Ambidextrous/31g/Carbon Fiber Composite Honeycomb Shell/PixArt Sensor with OnChip Motion Sync/Up to 8000Hz Wireless Polling/Cheetah Lion Tiger Sizes) Review
The Finalmouse UltralightX is a 31g ambidextrous wireless gaming mouse built around a carbon fiber composite honeycomb shell, a latest-generation PixArt sensor with OnChip Motion Sync, and up to 8000Hz wireless polling, available in Cheetah, Lion, and Tiger sizes.
Finalmouse mice are hype releases as much as they are hardware. The UltralightX is the brand's carbon fiber composite flagship — 31g is astonishingly light for a mouse with a rigid, non-flexing shell, and it's the lightest mouse in our entire catalog by a wide margin.
Sensor and Polling
Sub-300 microsecond click latency and up to 8000Hz wireless polling puts this at the bleeding edge of what's currently possible in a wireless mouse. This is built for players who genuinely notice the difference between 1000Hz and 8000Hz.
Weight and Shape
31g is close to a third lighter than most of the "ultralight" mice already in our catalog. The carbon fiber composite honeycomb shell is how Finalmouse gets there without the structural flex that plagues some drilled-shell competitors; strength-to-weight ratio is reportedly over three times better than standard ABS plastic.
Comparison to Alternatives
Against Pulsar's X2, also new here, the X2 weighs almost 70% more and costs a fraction of the price; most players are better served by the X2 unless the absolute lightest weight is the entire point. Against our own Logitech G Pro X Superlight 2, the Superlight 2 has far better availability and first-party software support; the UltralightX wins purely on raw weight and polling ceiling.
