The Finalmouse Starlight-12 Small is an exceptional ultra-lightweight, wireless gaming mouse. It has a honeycomb top shell made of a magnesium alloy, which not only makes it exceptionally lightweight but very sturdy-feeling. It has a fairly comfortable ambidextrous shape, but it's very small. It's well suited for all grip types for small and medium-sized hands. However, it should be comfortable for large hands using a fingertip grip as well. Performance-wise it has a high polling rate, a very low lift-off distance, and a very consistent sensor. Unfortunately, there isn't any companion software for customizing settings or programming buttons. Also, there are only four CPI presets to choose from, and while the click latency is good overall, it isn't as low as most other high-end wireless gaming mice.
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 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.

Test Results
The Finalmouse Starlight-12 Small has an ambidextrous, low-profile shape with two side buttons on the left and a honeycomb top shell made of a magnesium alloy. Our unit is the Achilles color variant. It has a gold and silver paint scheme with embossed filigree on the left and right-click buttons, the mouse wheel, and the CPI button. If you're interested in an all-blue colorway of this mouse, check out the Finalmouse Starlight-12 Poseidon Small.
Update 08/26/2021: After several weeks of everyday office use, the right-click button on our unit became stuck and stopped working. We contacted Finalmouse regarding the issue, and they responded with several suggestions. Firstly, they suggested we try clicking the button several dozen times. Doing this resolved part of the problem, but it now felt like our click button was rubbing against something rather than sticking. From there, Finalmouse suggested we open our mouse and attempt to clean the area under the right-click mechanism. After opening the mouse, we could see that there was a small black square normally glued to the underside of the right-click mechanism that had rubbed off, leaving a glue residue that caused our initial problem. We cleaned the excess glue off, and our right-click button works properly again. After experiencing this issue, we've decided to downgrade the build quality score from its initial score of 9 to 8.
The build quality of the Finalmouse Starlight-12 Small feels impressive. The top shell of the mouse is made of a magnesium alloy and feels extremely solid. Finalmouse warns that the bottom section isn't nearly as strong as it's made of Ultem, a kind of plastic that allows the wireless signal to escape. This underside section flexes when pressure is applied, but this is very unlikely to present any problems during regular use.
Note: We've been monitoring the number and frequency of users reporting build quality issues with the Starlight 12-Small. One of the most common complaints is that the right-click button sticks and stops working. We've experienced this issue on our unit and detailed it above. Another extremely common complaint is that of the scroll wheel being slightly off-centered to the right. This issue is present on both the Starlight-12 Small and Starlight-12 Medium units we tested and is easiest to see when looking at the mouse head-on using our 3D tool. This issue hasn't affected the normal use of the wheel on either unit, but some users have reported that the scroll wheel will occasionally register a scroll-up input while you're trying to scroll down. We will continue to monitor the situation and update our review as necessary.
According to Finalmouse, the Finalmouse Starlight-12 Small weighs 42 grams. They also note that the magnesium chassis can vary in thickness due to manufacturing complexities, and they note the actual weight of each mouse may vary by up to 2 grams.
The Finalmouse Starlight-12 Small has a relatively comfortable ambidextrous shape, but it isn't particularly ergonomic. It's a very small mouse in all dimensions, making it well-suited for smaller hands, but those with larger hands will likely find the Finalmouse Starlight-12 Medium a better fit.
Finalmouse claims the Finalmouse Starlight-12 Small has a continuous battery life estimated at 160 hours, an average use case life estimated at three weeks, a below-average use case life estimated at seven weeks, and an idle use case estimate of 16 weeks. However, this isn't something we test.
The Finalmouse Starlight-12 Small has an excellent cable. It has good flexibility and moves across desks with minimal drag.
The mouse feet glide very smoothly on all surfaces, but they make a slight scratching sound directly on desks.
