The Finalmouse Starlight-12 Medium is an exceptional ultra-lightweight, wireless gaming mouse. Its honeycomb top shell body is magnesium alloy, making it remarkably lightweight but also very sturdy-feeling. It has a comfortable ambidextrous shape well-suited for a palm or a claw grip for all but extra-large hands or a fingertip grip for all except for small hands. Performance-wise, it has a high polling rate, a very low minimum lift-off distance, and very low click latency. It doesn't have a CPI range nearly as broad as most other gaming mice, but most gamers likely won't find this a major issue. Unfortunately, you can only cycle between four preset CPI settings. Also, there isn't any customization software for re-programming buttons or adjusting other sensor settings.
Note: Finalmouse releases its mice in drops, so they're only available while supplies last. At the time of publishing, the Finalmouse Starlight-12 drop is over, and all units were sold. Although Finalmouse has pledged to produce more, it's unclear when this will be, and right now, you can only purchase them from third-party resellers, which is how we had to buy our unit.

Popular Mouse Comparisons
The medium-sized Finalmouse Starlight is a remarkable ultra-light gaming mouse. In many ways, along with its smaller version, it improves on the formula of Finalmouse's last release, the Finalmouse Ultralight 2 - Cape Town. The magnesium alloy shell feels much studier, and the Medium version weighs essentially the same as its predecessor, even with the addition of a rechargeable battery and wireless capability. That said, the Medium is likely the better choice for a broader range of people as its larger size makes it much more accomodating for more hand sizes.

The Finalmouse Starlight-12 Medium and the Finalmouse Starlight Pro - TenZ Medium are very similar mice in the same lineup. They share the same dimensions and weight but different visual designs. The Finalmouse Starlight Pro - TenZ is a more recent release and includes some minor manufacturing improvements related to build quality.
The Finalmouse Ultralight X and the Finalmouse Starlight-12 Medium are both lightweight, wireless gaming mice with the same shape and honeycomb body designs. Altogether, the UltralightX provides better raw gaming performance and is significantly lighter as it's made of a composite carbon fiber material, while the Starlight-12 is made of a somewhat heavier magnesium alloy. Additionally, the Ultralight X supports polling rates higher than 1000Hz, while the Starlight-12 has a maximum wireless polling rate of 1000Hz.
The Razer Viper Mini and the Finalmouse Starlight-12 Medium are outstanding wireless gaming mice. The Finalmouse has a honeycomb body made of magnesium alloy that's lighter and feels sturdier. It connects wirelessly with its USB receiver, and it has a lower lift-off distance. Unfortunately, it has no RGB, no customization software, and no internal storage compartment for its USB receiver. On the other hand, the Razer is a wired-only mouse with a solid plastic body. It has a wider CPI range, an adjustable CPI, and lower click latency. It also has customization software, though it's only compatible with Windows.
The Logitech G PRO X SUPERLIGHT and the Finalmouse Starlight-12 Medium are comparable, wireless ultra-light gaming mice. The Finalmouse is lighter and feels sturdier, but it only has four default CPI settings. Comparatively, the Logitech has mouse feet that glide more smoothly, a much wider CPI range, and an adjustable CPI. It also has customization software, which the Finalmouse lacks.
Test Results

The medium Finalmouse Starlight-12 has an ambidextrous, low-profile shape and two side buttons on the left. Its honeycomb body is magnesium alloy, and our unit is painted in the Hades color scheme. Most of the mouse is painted black, and it has embossed gold filigree towards the front of the mouse and silver accents between the left and right-click buttons and on the scroll wheel. If you're interested in a different, all-blue colorway for this mouse, see the Finalmouse Starlight-12 Poseidon Small. Or, if you prefer a silver colorway, check out the Finalmouse Starlight Pro - TenZ Medium.
The medium Finalmouse Starlight build quality feels outstanding. The top shell is made of magnesium alloy and feels extremely sturdy. Finalmouse warns that the underside isn't nearly as strong as it's Ultem, a kind of plastic that lets the wireless signal escape. This bottom panel flexes when pressure is applied, but this is unlikely to present any problems during everyday use.
Note: The scroll wheel on our unit is very slightly off-centered to the right. This seems to be a fairly common issue that other users and online reviewers have experienced, but it doesn't affect the normal function of the scroll wheel. This issue is also present on the Finalmouse Starlight-12 Small unit that we tested. Some users have also reported that the scroll wheel will occasionally register a scroll-up input while you're trying to scroll down, but we haven't experienced this issue. Another frequently reported issue is that the right-click button can stick and stop working. While this issue isn't present on our Starlight-12 Medium, we've experienced this issue on our Starlight-12 Small unit and have detailed our experience in the Build Quality section of that review. We will continue to monitor and report on quality control issues as necessary.
According to Finalmouse, the medium Finalmouse Starlight-12 weighs 47 grams. The magnesium chassis may vary in thickness due to the manufacturing process, and they indicate the actual weight of each mouse may vary by up to 2 grams. We obtained an exact weight of 49.4g.
If you're interested in a wireless gaming mouse that's even more lightweight with an identical size and shape but with a body made of carbon fiber composite, check out our review of the Finalmouse UltralightX.
The medium Finalmouse Starlight has an ambidextrous shape that's likely slightly more comfortable for most people than its smaller counterpart due to its larger size. However, those with smaller hands may still prefer the Finalmouse Starlight-12 Small.
Finalmouse claims the medium Finalmouse Starlight-12 has a battery life of 160 hours, an average use life estimated at three weeks, a below-average use life estimated at seven weeks, and an idle use estimate of 16 weeks. However, this isn't something we test. There's a light inside the mouse that flashes when the battery is low.
The cable on the medium Finalmouse Starlight-12 is excellent. It's flexible, doesn't retain kinks from packaging, and moves with minimal drag across desks.
The buttons aren't reprogrammable as there isn't any configuration software. The two side buttons function as front and back buttons by default, and the button below the scroll wheel allows you to cycle through the four CPI presets.
The medium Finalmouse Starlight-12 has great click latency. It provides a responsive-feeling experience for both casual and competitive play.
The medium Finalmouse Starlight-12 has four preset CPI settings of 400, 800, 1600, and 3200. You can cycle between these presets with the button behind the scroll wheel.

Note: The scroll wheel on our unit is slightly off-center towards the right. Other users and online reviewers have also reported this issue. We found it didn't affect the normal use of the mouse in any way.
