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. At the time of writing, it supports a maximum wireless polling rate of 4000Hz. Finalmouse has stated that they're working on releasing a firmware update to increase the maximum wireless polling rate to 8000Hz in the future.
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 below.
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.

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.

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. The label of our unit 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.

Compared To Other Mice
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.
For more recommendations, see our picks for the best lightweight mouse, the best FPS mouse, and the best wireless gaming mouse.
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 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 Endgame Gear OP1 8k are lightweight, high-performance gaming mice with symmetrical shapes. While the Endgame Gear is wired, the Finalmouse is wireless and weighs less. It features a honeycombed shell made of carbon composite material. The Finalmouse is flexible and makes creaking sounds under pressure, while the Endgame Gear feels rock solid. The two mice have outstanding performance overall, with the main difference being that the Endgame Gear supports a higher maximum polling rate of 8000Hz compared to the Finalmouse's lower 4000Hz polling rate.
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 ULX Pro Series and the Ninjutso Sora V2 are lightweight wireless gaming mice with symmetrical shapes. The Finalmouse is marginally lighter thanks to its smaller size and carbon composite honeycombed shell. That said, the difference in weight is minor compared to the delta in build quality; the Finalmouse flexes and creaks with pressure, while the Ninjutso feels solid. The two perform very similarly, but the Ninjutso mouse has a maximum polling rate of 1000Hz while the Finalmouse has a maximum polling rate of 4000Hz.
Test Results
This mouse has a carbon fiber composite body with honeycomb cutouts on the sides, top, and bottom. The main click buttons have debossed/engraved linework patterns with contrasting color accents. There aren't any visible logos or RGB lighting on this mouse.
Note: The 3D scanning tool has difficulty accurately capturing depth inside this mouse's honeycomb body. As a result, the scan displays a blurry texture layer inside the mouse. That said, the scale and dimensions of this scan are still accurate and aren't affected by this minor visual error.
This mouse isn't designed specifically for portability. While it isn't very big, it's somewhat bulky and lacks a compartment for storing its USB receiver. Additionally, its honeycomb design leaves the interior more open to collecting dust and debris.
The Finalmouse ULX Pro Series has good build quality overall. The body is made of a carbon fiber composite material with a 'ProGrip' coating that feels grippy and high-quality. According to Finalmouse, their carbon fiber composite has a much better strength-to-weight ratio than conventional ABS plastic or magnesium alloy, as used on their previous lineup of Finalmouse Starlight-12 mice.
While this material feels very high-quality, it's also quite flexible. Applying intentional pressure anywhere on the mouse causes it to bend slightly and make audible creaking sounds, especially at seams when panels meet. Also, applying pressure to the bottom plate under the right-click button causes it to separate from the side panel. Here is a video of the issue.
The main click buttons are lightweight but somewhat mushy-feeling with significant post-travel. The side buttons also have significant play and feel mushy.
We bought and tested the small (Cheetah) size variant of the Finalmouse ULX Pro Series. An additional medium (Lion) and large-sized (Tiger) variant is also available. For more details, see the Differences Between Variants section above.
Below, we've listed the advertised weights of all three sizes as found on this mouse's product page.
- Cheetah (Small): 31 grams
- Lion (Medium): 35 grams
- Tiger (Large): 37 grams
Finalmouse states that approximate weights are measured without skates and may have a variance of +-2g from unit to unit.
The Finalmouse ULX Pro Series has a fairly low-profile, symmetrical shape with a small, centered hump and gently sloping sides. Its shape is best suited for claw and fingertip grip types.
We bought and tested the small-size variant (Cheetah), which shares the same dimensions as the small-size Finalmouse UltralightX (Cheetah) and Finalmouse Starlight-12 Small and best suits medium- or small-sized hands.
There are two larger variants, the Lion (Medium) and the Tiger (Large). For more details about these size variants, see the Differences Between Variants section.
This mouse has a 250mA battery. While Finalmouse doesn't specify a battery life estimate, they state that the "same technologies in the standard UltralightX are utilized in the ULX Pro Series" and that "gamers can expect to reach an average of two months without needing to charge their ULX" on the UltralightX's product page. We expect this estimate to be optimistic, assuming low daily usage and likely using a 1000Hz polling rate.
The battery life you can expect will depend highly on average daily usage and the polling rate you choose, as higher polling rate settings consume significantly more battery life. If you have a fairly high (5+ hours) of daily usage at polling rates higher than 1000Hz, we expect you may need to recharge your mouse as often as every few days.
If you have this mouse and want to share your experiences with its battery life, we'd love to hear from you in the comments.
This mouse includes a braided charging cable. It's quite stiff and drags somewhat on desks and mousepads. This cable is noticeably less flexible and made of a cheaper-feeling material than the cable included in other recent Finalmouse releases, like the cable included with the Finalmouse Starlight Pro - TenZ Medium.
This mouse's feet glide very easily on mousepads with only marginal felt friction when used directly on desks or harder mousepads. The feet have some sharp edges, but this doesn't noticeably add any drag due to the lightweight nature of this mouse. Third-party replacement feet are also available.
- Wireless receiver dongle (USB-C)
- Braided cable (USB-C to USB-A)
- Pro Series XGRIP adhesive grips
- User documentation
If you want to reprogram any of this mouse's buttons, you'll need to use third-party software, as the XPANEL web-based configuration client doesn't support button mapping.
There's a power switch on the bottom of the mouse.
The Finalmouse ULX Pro Series has exceptionally low and consistent click latency performance. It delivers an exceptionally responsive-feeling experience for playing games in any genre and at any competitive level.
We performed our click latency testing at a polling rate of 4000Hz, which is the current maximum polling rate at the time of writing.
The Finalmouse ULX Pro Series offers exceptional CPI performance. Its sensor delivers outstanding tracking accuracy, and the physical movements you make with your mouse translate extremely close to your cursor movements on-screen.
This test was conducted with a polling rate setting of 4000Hz, which is the current maximum polling rate at the time of writing.
The Finalmouse ULX Pro Series provides outstanding sensor latency performance. The sensor reacts exceptionally quickly when you move your mouse, and these movements almost perfectly match the timing of the cursor movements you see on the screen.
We performed our primary sensor latency testing with the Motion Sync setting toggled off.
We performed supplementary testing with Motion Sync on and found the sensor latency to be slightly lower, which is somewhat unusual as most implementations tend to add a small degree of latency. On the Finalmouse ULX Pro Series, with the Motion Sync setting on, the results are as follows:
- Delay To Start Of Movement: 10.0 ms
- Delay At Half Movement: 1.1 ms
- Delay To End Of Movement: 0.0 ms
We performed all tests with the polling rate set to 4000Hz, which is the maximum setting available at the time of writing.
Note: The latency CPI graph above lacks data for the 6000 CPI setting because this mouse only has five fixed CPI settings and doesn't have a 6000 CPI preset.
While this mouse advertises a minimum lift-off distance of 1mm in the software, we found it to be 2.4mm in our testing. We retested this multiple times to verify but observed the same results. We expect this to be a firmware issue and plan on a retest if Finalmouse issues an update. Let us know in the comments if you've encountered the same behavior.
At the time of writing, the polling rate options are 500Hz, 1000Hz, 2000Hz, and 4000Hz. Finalmouse states that this mouse supports a maximum wireless polling rate of 8000Hz, but this feature remains in testing at the time of writing. Finalmouse has said they'll release a firmware update to increase the polling rate to 8000Hz. We plan on retesting this mouse once the update is released.
This mouse has five fixed CPI settings: 400, 800, 1600, 3200, and 6400. With the web-based configuration client, you can toggle between CPI presets, polling rates, and lift-off distances.
This mouse's scroll wheel operates quietly and feels reasonably precise, with defined notches between steps. However, the surface finish isn't very grippy compared to more textured or rubberized scroll wheel surfaces on many other gaming mice, including the Finalmouse Starlight-12 Poseidon Small. You may find the finish slippery, especially if your hands tend to sweat more.
The left- and right-click buttons, side buttons, and scroll wheel operate quietly and are unlikely to bother anyone around you.
The Finalmouse ULX Pro Series uses XPANEL, which is a web-based configuration client that you can access from Finalmouse's website here. This utility lets you choose between polling rates, lift-off distance options, and five CPI presets. You can also toggle Motion Sync and adjust the LED behavior on the wireless receiver dongle. You can also download a desktop version of the software for Windows or Linux.
