Unmatched Performance
The Rival 300S performance reigns over the competition thanks to a cutting edge sensor, newly developed SteelSeries switches, and a suite of tweaks to give you the edge over your rivals.
Unrivaled Design
The mouse professional gamers depend on, just got better. While designing the Rival 300S , we kept everything you loved about the original Rival and added several improvements.
Endless Customization
Rival 300S is incredibly customizable with 16.8 million color, 2-zone illumination, a 3D printable nameplate for individuality, and SteelSeries Engine 3 for finely-tuned performance adjustments.

Advanced Optical Sensor
At the heart of Rival 300S is the Pixart PMW3310 optical sensor. The 3310 promises zero hardware acceleration, offering true 1:1 tracking and precise movements no matter how fast things get during the heat of battle. The CPl is best-in-class with adjustments from 50 to 7200.
SteelSeries Switches
The proprietary SteelSeries engineered switches have a lifetime of over 30 million clicks and are the high-speed conduit between the sensor and mouse clicks. The audible mouse click is subtle, while delivering quick, tactile responsiveness.
Fine Tuning
When it’s time to get competitive you can really dial-in your settings thanks to SteelSeries Engine 3. Adjustable CPl, programmable buttons, polling rate, angle snapping, acceleration and deceleration are among the customizations that will make the mouse perform as you see fit.

Forged by Victory
Rival 300S shape was molded from some of the . most iconic gaming mice of the past. We took great lengths to ensure a comfortable fit thanks to the right-handed orientation, a raised back end, and sleek contours.
Refined Side Grips
SteelSeries engineers have gone to great lengths to create the best possible side grip for the Rival 300S We went back to the drawing board and sculpted new side grips from a more durable and dense material that is more resistant to sweat and abrasion.
Ergonomic Buttons
No one wants to do finger gymnastics just to press a button on their mouse. We engineered Rival 300S with ergonomic button positioning and size so clicks and movements feel natural, quick, and don’t take away from gameplay.

Brilliant Illumination
Rival 300S features two independent lighting zones that are capable of 16.8 million colors. Colors can be adjusted in each zone, per specific profile, game or application. Four brightness levels and three lighting effects to choose from-Steady, Color Shift and Breathe-will help make your Rival 300S your own.
SteelSeries Engine 3
SteelSeries’ software suite is where you take control of the mouse and its many features. This new version of SteelSeries Engine 3 gives users a unified application to control all of their SteelSeries products, offers cross platform support, and will feature a cloud syncing system to make sure you always have your Rival 300S settings.
3D Printable Name Plate
Handy with a 3D printer? Why not design your own Rival 300S nameplate? To switch out the nameplate, simply pry the existing one off at either end (a fingernail or the tip of a pen can do the trick) and pop your new one in.
