The Finalmouse ULX Frostlord continues the Finalmouse UltralightX series of wireless gaming mice. Finalmouse frequently releases iterative versions of its mice, but differences between releases are often minor, typically limited to new colorways, small build quality adjustments, and firmware updates. The ULX Frostlord is very similar to the Finalmouse UltralightX Competition, which we've reviewed separately. As a result, we've only added brief notes in this review where this unit differs.
This mouse was released in a single drop, limited to 10,000 units, and was available in Small, Medium, and "Classic" sizes. It's no longer available directly from Finalmouse and is now only found on the aftermarket. We tested a Medium unit. See the Differences Between Variants section for more details.
Our Verdict
The Finalmouse ULX Frostlord isn't primarily designed for work, but it's perfectly acceptable for it. It only lacks some more common productivity features, such as a secondary scroll wheel or power-saving Bluetooth connectivity.
Scroll wheel makes minor creaking noise and occasionally feels like it slips out of its detentes when scrolling upwards quickly.
Can't reprogram buttons without third party software.
Doesn't support Bluetooth; no multi-device pairing.
The Finalmouse ULX Frostlord is an outstanding FPS gaming mouse. Its carbon fiber composite body is extremely lightweight while remaining very sturdy. It delivers exceptionally low click latency, remarkably low sensor latency, and supports a maximum wireless polling rate of 8000Hz, resulting in a highly responsive and consistent in-game experience. Its main downsides are the honeycomb cutouts on the top shell, which may irritate you if you're sensitive to the uneven surface feel on your palm. We also noted minor creaking in the scroll wheel with occasionally mushy scroll steps.

The Finalmouse ULX Frostlord is decent for playing MMOs, but doesn't have as many side buttons as a typical dedicated MMO mouse, and its software doesn't support button remapping. That being said, it has excellent overall build quality and outstanding raw performance.

Significantly fewer side buttons compared to dedicated MMO gaming mice.
The Finalmouse ULX Frostlord delivers superb raw performance. It has exceptionally low click latency, remarkably good sensor latency, and supports a maximum wireless polling rate of 8000Hz, ensuring more consistent overall performance over a standard 1000Hz polling rate. However, using higher polling rates also consumes battery power much more quickly.

Popular Mouse Comparisons
Finalmouse indicates that the Finalmouse ULX Frostlord is the final release in its UltralightX series. Aside from its new white colorway and unit-to-unit variation in build quality and small differences in performance results, it's effectively identical to the previous iteration in the series, the Finalmouse UltralightX Competition.

The Finalmouse UltralightX Competition and Finalmouse Ultralight ULX Frostlord are extremely similar iterative models in the same series. The ULX Frostlord is newer, and they have different colorways, but both perform virtually identically. While the UltralightX Competition unit we tested suffered from considerable build quality issues, including panel flex, creaking, and popping noises, the ULX Frostlord we tested has much better overall build quality, although its scroll wheel occasionally creaks and feels like it almost slips past detents when scrolling quickly, making scroll steps feel mushier.
The Finalmouse UltralightX and the newer Finalmouse Ultralight ULX Frostlord are iterative models in the same series. The UltralightX Competition introduces minor changes, including solid side panels instead of honeycomb side panels and small build quality improvements, but they perform virtually identically. Unfortunately, we experienced mushy and inconsistent button feel on the original UltralightX, and while the overall build quality is better on our unit of the ULX Frostlord, the scroll wheel creaks and occasionally feels like it may be slipping slightly past detents when scrolling quickly upwards.
The Razer Viper V3 Pro and the Finalmouse ULX Frostlord are lightweight, wireless gaming mice designed for high-level competitive play and similarly outstanding raw performance. The Razer has solid plastic body, while the Finalmouse has a carbon fiber composite body with honeycomb cutouts and is noticeably lighter as a result.
The Logitech G PRO X SUPERLIGHT and the Finalmouse ULX are lightweight wireless gaming mice designed for competitive play. While the Logitech has a solid plastic body, the Finalmouse has a carbon fiber composite body with weight-saving honeycomb cutouts and is noticeably lighter. Both mice have outstanding performance, but the Finalmouse performs slightly better, with support for a higher maximum polling rate of 8000Hz.
