The Finalmouse ULX Pro Series is a lightweight wireless gaming mouse. The Tarik edition that we bought and tested is the first release of the limited Pro Series lineup based on Finalmouse's UltralightX. It features the same symmetrically shaped body, PixArt PAW3395 sensor, and carbon fiber composite construction but features a new soft touch "ProGrip" coating. It also uses Huano Blue Shell Pink Dot switches for its main click buttons and supports a maximum polling rate of 8000Hz.
You can buy this mouse in three sizes: small (Cheetah), medium (Lion), and large (Tiger). We bought and tested the small (Cheetah) size variant. For more details, see the Differences Between Variants section.
Note: The ULX Pro Series is being released in limited edition runs. The Tarik edition we bought is sold out at the time of publishing, so you can only purchase one from third-party resellers. Finalmouse has teased that they'll release more ULX Pro Series limited edition models in the future.
Our Verdict
The Finalmouse ULX Pro Series is acceptable for work but isn't designed explicitly for this usage. That said, it's very lightweight and has a comfortable symmetrical shape. Unfortunately, while you can connect to it wirelessly with its USB receiver, it doesn't support Bluetooth or multi-device pairing. Also, while it has a web-based configurator, you can't remap buttons without third-party software. Lastly, the scroll wheel feels cheap and lacks helpful productivity features like L/R tilt inputs and free-scrolling.
- Connects wirelessly with its 2.4GHz receiver.
- Remarkably lightweight; less fatiguing to use for long stretches compared to heavier productivity mice.
- Carbon fiber body is noticeably flexible.
- Can't reprogram buttons without third party software.
- Doesn't support Bluetooth; no multi-device pairing.
- Scroll wheel lacks a free-scrolling mode and L/R tilt inputs.
The Finalmouse X Tarik ULX Pro Series is a remarkable FPS gaming mouse. Its carbon fiber composite body makes it remarkably lightweight and easy to move quickly and accurately. It also has incredibly low and consistent click latency and outstanding all-around sensor performance that's more than suitable for gaming at any competitive level. Unfortunately, it also suffers from some build quality issues. While its body is very strong, it's noticeably flexible. If you apply pressure to the underside, you can separate the side panel from the bottom panel. Also, all of the buttons feel fairly mushy and have a cheap feel. While these issues are noticeable, we don't expect them to impact your in-game performance negatively. For more details about these issues, see the Build Quality section.

- Incredibly low and consistent click latency performance.
- Outstanding all-around sensor latency and accuracy.
- Carbon fiber body is noticeably flexible.
- All buttons feel mushy; main click buttons have noticeable post-travel.
The Finalmouse ULX Pro Series is okay for MMO gaming but has fewer side buttons than a dedicated MMO gaming mouse, and you can't remap buttons without third-party software. That said, it's exceptionally lightweight and has incredibly low and consistent click latency and outstanding sensor performance, providing an exceptionally responsive-feeling in-game experience.

The Finalmouse ULX Pro Series delivers superb raw performance. Its click latency is incredibly low, and the sensor latency and accuracy are outstanding. This mouse also supports a maximum wireless polling rate of 8000Hz, delivering slightly better and more consistent overall performance over a standard 1000Hz polling rate. However, using higher polling rates also requires considerable CPU resources and consumes battery power much more quickly.

Differences Between Sizes And Variants
The Finalmouse ULX Pro Series is available in three size variants: small (Cheetah), medium (Lion), and large (Tiger). We bought and tested the small (Cheetah) variant. Our unit's label is here. The label is mostly obscured because it's on the inside of the mouse and partially blocked by the honeycomb exterior. The model number on our unit is S/N: SA241704063.
We expect all size variants to perform similarly, and we expect most of our tests will broadly apply to all sizes except for obvious tests like Shape and Weight.

Popular Mouse Comparisons
The Finalmouse ULX Pro Series is a limited-edition lightweight wireless gaming mouse based on the Finalmouse UltralightX. It shares the same symmetrical shape, honeycombed carbon-composite shell, and PixArt PMW3395 sensor. The main differences are the new colorway, Huano Blue Shell Pink Dot switches for the main click buttons, and a soft-touch "Pro Grip" coating on the shell.
This mouse is incredibly lightweight and has outstanding performance. It competes with other flagship gaming mice like the Razer Viper V3 Pro, Logitech G PRO X SUPERLIGHT 2, and Ninjutso Sora V2. Unlike those mice, which all have solid plastic shells and minimal aesthetics, the ULX Pro Series has a distinctive colorway and a honeycomb outer shell, which leaves its inside exposed. While extremely lightweight, it suffers from flex and creaking throughout the body.
Unlike the UltralightX it's based on, Finalmouse has indicated that this mouse will be released in limited edition runs like previous Finalmouse models. We bought and tested the Tarik edition, but Finalmouse has teased that future pro models will be added to the lineup.

The Finalmouse ULX Pro Series is an ultra-lightweight gaming mouse based on the Finalmouse UltralightX. The mice share the same sensor, 4000Hz maximum polling rate, and carbon composite body with honeycomb-shaped cutouts. The ULX Pro Series is a limited edition mouse released in different color variants than the UltralightX, while Finalmouse has committed to keeping the latter in continuous production.
The Finalmouse ULX Pro Series and the Razer Viper V3 Pro are both lightweight, high-performance wireless gaming mice. The Finalmouse is much lighter than the Razer due to its carbon-composite shell with honeycomb-shaped cutouts. However, the Razer has better build quality and a more traditional design with a solid plastic shell. Overall, the two mice perform similarly, but at the moment, the Razer supports a higher maximum polling rate of 8000Hz, while the Finalmouse's maximum polling rate is only 4000Hz.
The Finalmouse ULX Pro Series and the WLmouse Beast X are ultra-lightweight wireless gaming mice with nearly identical symmetrical shapes. The Finalmouse is made of a carbon fiber composite and has slightly better raw performance. The WLmouse has a magnesium alloy body and has better overall build quality with fewer squeaks and less flexing. Additionally, the WLmouse is more readily available as it's in continuous production, whereas the Finalmouse was a limited run, and all units were sold at the time of writing.
The Finalmouse UltralightX Competition and the Finalmouse ULX Pro Series are very similar, limited edition versions in the same lineup. Both versions have a composite carbon fiber body with weight-saving honeycomb cutouts on the top and bottom. The UltralightX Competition has solid sides while the ULX Pro Series has cutouts on its sides. The UltralightX Competition has a slightly higher-quality scroll wheel encoder and only comes in a dark gray colorway, while the ULX Pro Series has several two-tone colorway options. Unfortunately, both have somewhat inconsistent build quality. We experienced a mushy button feel on the ULX Pro Series we tested and noticeable flexibility, popping, and creaking in the body of the UltralightX Competition we tested.
