At the end of the 1990s, when most PC mice were beige, ball-based, and capped at a few hundred DPI, the original Razer Boomslang showed up with a weird snake-head shape and a 2,000-DPI mechanical sensor. Razer now calls it the world’s first gaming mouse, and whether or not you want to argue that title, it definitely helped turn the mouse from a beige accessory into a performance peripheral that people obsessed over.
The Boomslang 20th Anniversary Edition is Razer’s way of revisiting that moment with twenty years of hindsight. It is a one-time release limited to 1,337 units worldwide, each uniquely serialized, with the #1337 unit reserved as a “leet” nod for one lucky fan. It is aimed squarely at people who either owned the original or wished they had, but it is also a fully modern mouse that can live on a current desk without feeling like a prop.

On the outside, the new Boomslang keeps the iconic snake-head outline and true ambidextrous form, preserving the low, wide body that made the original stand out. The translucent shell and underglow are deliberate echoes of that first model, but the lighting is now a nine-zone Razer Chroma RGB system that can be tuned in Synapse. The idea is that, at a glance, it still reads as a Boomslang first, and as a spec sheet second.
Inside, everything is from 2025. The Razer Focus Pro 45K optical sensor offers up to 45,000 DPI with 99.8 percent resolution accuracy, a ridiculous number compared to the original’s 2,000-DPI ball. HyperPolling Wireless pushes the polling rate up to 8,000 Hz, which means the mouse can report its position to the PC eight thousand times per second. Gen-4 optical switches handle primary clicks with a 100-million-click lifespan and no debounce delay.
Charging and connectivity also get a full reboot. The mouse is fully wireless and ships with a Razer Mouse Dock Pro that acts as both a magnetic charging base and a dedicated wireless receiver. Drop the Boomslang on the dock, and it starts charging automatically, while the dock handles HyperPolling Wireless up to 8,000 Hz over a single USB cable. It is a neat contrast to the wired-only original that helped define the gaming-mouse category.
Material and feel have been nudged into more premium territory. The primary buttons are wrapped in PU leather for extra grip and a more tactile press, which is a small but noticeable change if you are used to hard plastic shells. Underneath, nine zones of Chroma underglow can be customized with 16.8 million colors and effects, and eight programmable controls can be mapped to macros and profiles in Synapse.
The Boomslang 20th Anniversary Edition is a reminder that the idea of a gaming mouse had to be invented once, by a translucent, snake-shaped oddball that rolled a ball at 2,000 DPI. This remake uses that nostalgia to show how far sensors, switches, and wireless tech have come. For anyone who grew up on early Razer gear, it is a small, serialized time machine that also happens to be a high-end mouse in 2025.
