Ergonomic Design Every aspect of the Rival 310 design meets esports players' stringent demands for comfort. Whether you deploy a claw grip or palm grip, the shape will provide perfect comfort for long & intense gaming sessions. Split-Trigger Buttons While most mice use one piece of plastic from front to back, the Rival 310 features our exclusive split-trigger button design, first introduced in our flagship Rival 700 gaming mouse. Splitting the triggers provides excellent click force & consistent feel during burst firing, rapid presses or holds. Settings On-The-Go Save all your performance & lighting settings directly to the mouse. A Powerful 32-bit ARM processor means that you can save CPI settings, button remappings & lighting effects on-board for software-free use at LAN events & tournaments. Prism Sync Enabled Sync dynamic multi-color lighting effects between all your Steel Series Prism-enabled gear. From one-click lighting effects to complex light shows, Prism Sync gives you the power to level-up the style of your battle station.
