The Finalmouse Starlight-12 Phantom Small is an ultra-lightweight, wireless gaming mouse. It's a continuation of the Finalmouse Starlight-12 lineup, so it has the signature magnesium alloy shell with a honeycomb design to keep the weight very light. At 44.5g, it's one of the lightest mice we've ever tested, and it features newer Kailh 8.0 switches and some minor adjustments to the manufacturing process to address quality control concerns in previous Starlight-12 models. Its small, symmetrical shape is well-suited for small and medium hands using any grip type. Performance-wise, it uses Finalmouse’s proprietary Finalsensor. It has excellent click latency, a very low minimum lift-off distance, and four CPI presets. However, there's no companion software, so you can't adjust the sensor settings or reprogram any buttons.
Note: Finalmouse releases its mice in drops, meaning they're only available until stock runs out. At the time of publishing, the Finalmouse Starlight-12 Phantom drop is over, and all units were sold. Currently, you can only purchase them from third-party resellers, which is how we had to buy our unit.
Our Verdict

Compared To Other Mice
The Finalmouse Starlight-12 Phantom is a continuation of the Starlight-12 lineup with a new colorway, some minor tweaks to the manufacturing process, new Kailh 8.0 switches, and a few adjustments to address some of the most common quality control issues present on mice in the original drop. At 44.5g, it's one of the lightest mice we've tested, and its size and shape are comparable to other ultra-light Finalmouse offerings like the Finalmouse Starlight-12 Small. As many users have reported, the scroll wheel is slightly off-center, though this doesn't impact the normal operation of the mouse.

However, the Phantom is the newest release in this Starlight-12 lineup and features a new colorway and newer Kailh 8.0 switches on its L/R buttons. The Phantom also addresses some of the quality control issues that appear on the Starlight-12 Small, like the right-click button. In terms of performance, the Phantom and the Starlight-12 perform similarly well, but the Phantom has somewhat better click latency.
The Razer Viper Ultimate and the Finalmouse Starlight-12 Phantom Small are both wireless gaming mice, but the Viper performs better overall. The Viper has better click latency, a significantly wider CPI range, and more side buttons. Also, it has RGB lighting. On the other hand, the Phantom weighs 31g less and feels more solid thanks to its magnesium alloy shell. While the Viper has companion software to remap buttons and adjust sensor settings, the Phantom doesn't.

It comes with companion software that allows you to adjust sensor settings or remap buttons, which the Finalmouse lacks.
Test Results
The Finalmouse Starlight-12 Phantom has a symmetrical, low-profile shape with two black plastic buttons on the left side. Its honeycomb shell is made of magnesium alloy with a black, silver, and blue color scheme and silver paint splatter accents. The L/R click buttons and the scroll wheel have embossed accents on them. While there's no RGB lighting, there's a light inside the mouse that will change colors according to the battery life. If you're interested in an all-blue color scheme for this mouse, check out the Finalmouse Starlight-12 Poseidon Small.
The Finalmouse Starlight-12 Phantom in the small size is approximately 1mm longer than the Finalmouse Starlight-12 Small since the small plastic piece above the scroll wheel tapers off to a slight point rather than a blunt edge.
The Finalmouse Starlight Phantom has a superb build quality. The top shell is a sturdy magnesium alloy, and the bottom is made of a strong plastic called Ultem, which allows the wireless signal to escape. The bottom flexes slightly when you apply pressure, but this shouldn't be noticeable during everyday use. The Kailh 8.0 switches in the L/R buttons feel satisfying and clicky, and the side buttons also feel good to press. The CPI button behind the scroll wheel is very stiff compared to the same button on our Finalmouse Starlight-12 Small, and it requires significant force to press. This seems to be a relatively common issue reported by users online, though it seems Finalmouse may have made this design alteration intentionally to prevent accidental CPI changes. Like other Finalmouse Starlight-12 units we've tested, our unit's scroll wheel is off-center to the right; however, this doesn't impact the normal operation of the mouse.
According to Finalmouse, the small Finalmouse Starlight-12 Phantom weighs 42 grams. They also note that due to manufacturing complexities with the magnesium chassis, the actual weight may vary by up to 2 grams.
The Finalmouse Starlight Phantom Small has a symmetrical shape that feels relatively comfortable. Its small size makes it well-suited to users with small or medium hands, so those with large or extra-large-sized hands may find it uncomfortable to use for long periods. Though there are no side grips, it doesn't feel slippery in hand. There's a larger version of this mouse, the Finalmouse Starlight-12 Phantom Medium, that's better suited for users with larger hands.
This mouse is not well-suited for users with large or extra-large-sized hands as your fingers extend past the front of the mouse using this grip.
This mouse is not well-suited for a claw grip if you have large or extra-large-sized hands, as the mouse's small size requires you to curl your fingers at an uncomfortable angle.
Users with extra-large hands may feel uncomfortable using this mouse with a fingertip grip due to its small size.
Finalmouse claims that the Finalmouse Starlight Phantom has a continuous battery life of around 160 hours, an average use case life estimated at three weeks, a below-average use case life is estimated at seven weeks, and an idle use case life of 16 weeks. There's also a light inside the mouse that flashes when the battery is getting low.
The cable is excellent. It's flexible and doesn't retain kinks from the packaging. It also moves with minimal drag across desks and mousepads.
The feet glide smoothly on all surfaces, but they're slightly scratchy on desks.

Using the CPI button behind the scroll wheel, you can cycle through four preset CPI settings; however, as we mentioned in our build quality tests, the CPI button is very stiff to press. There are two side buttons, which are bound to forward and backward by default, and a switch on the bottom to turn wireless mode on or off. Unfortunately, none of the buttons on the small Finalmouse Starlight Phantom are reprogrammable as there isn't any companion software.
This mouse has excellent click latency. It's more than suitable for achieving an extremely responsive-feeling gameplay experience in any game genre, including fast-paced and competitive games.
This mouse has four preset CPI settings of 400, 800, 1600, 3200, which you can cycle through using the CPI button behind the scroll wheel.
The mouse wheel feels precise and offers a smooth scroll experience with well-defined steps. It's fairly quiet but has a satisfying click when pressed.
Note: Like with previous Finalmouse Starlight-12 offerings, the scroll wheel on our unit is slightly off-center towards the right. It's a common issue that's been reported by many users. Fortunately, this issue doesn't affect the normal use of the mouse.
There's no companion software available for the Finalmouse Starlight Phantom.
