This article covers Finalmouse starlight-12 poseidon ファイナルマウス スターライト-12 ポセイドン Mサイズ Medium.

Overview

The Finalmouse Starlight-12 Poseidon Medium is the final release in the Greek mythology-inspired Starlight series. Weighing just 47 grams, it features a magnesium alloy shell that delivers extreme lightweight without compromising durability. Equipped with a high-precision optical sensor and premium PTFE feet, it offers excellent tracking and smooth glide. Limited to 10,000 units worldwide, this mouse has become a sought-after collector's item among competitive gamers.

Connectivity & Compatibility

This mouse connects via a wired USB interface. The cable is the flexible Finalmouse Infinity Cable (paracord-like braided cable), designed to minimize drag. It is compatible with Windows XP and newer, as well as Linux, with plug-and-play functionality. The ambidextrous shape with three buttons (left, right, scroll wheel) makes it suitable for both left- and right-handed users. There are no side buttons.

Product Info

Released on April 14, 2022, the Starlight-12 Poseidon Medium was manufactured in a limited run of 10,000 units. Original retail price was around $150, but current market prices vary significantly due to scarcity—often seen around ¥100,000 on Japan. Warranty typically covers one year from the store. Accessories include the mouse, extra PTFE feet, and stickers. It sits firmly in the high-end tier, targeting competitive players who demand the lightest possible mouse.

Best Use Cases

This mouse is ideal for competitive FPS and battle royale players who need quick, precise aim adjustments. The 47g weight reduces hand fatigue during long gaming sessions, allowing sustained performance. It also appeals to collectors willing to pay a premium for limited-edition peripherals. However, with only three buttons and a wired design, it is less suitable for MMO or productivity users who require additional inputs. If you need side buttons, consider a multi-button alternative.
