If you're looking for a big mouse with a narrow front base, the Rival 300 by SteelSeries is the gaming mouse for you!
The SteelSeries Rival 300 is the big brother of the SteelSeries Rival 100 and also a right handed ergonomic gaming mouse.
The Rival 300 has rounded left and right sides to rest your thumb and pinky fingers, as well as wide left and right button areas.
The built-in sensor in the Rival 300 is different to the Rival 100 (3059-SS optical gaming sensor) and performs better too.
Rival 300's Pixart PMW3310 optical sensor has zero mouse spin-out and it's very responsive with little delay.
The Rival 300 performs great between 400 DPI and 3200 DPI, offering a responsive gaming experience which is also helped by the buttons having tactile feedback with little travel time. The left and right buttons have a lift off distance of around 1.5mm, while the side buttons offer a snappy response.
The scroller is smooth, while the DPI button is nicely positioned between the left and right mouse buttons, preventing your fingers from slipping and accidentally pressing the DPI button. The DPI button itself allows you to set different DPI settings on the go.
The side grips of the mouse are really grippy thanks to rubber hedgehog-like side grips that allow you to nicely grip the mouse, even with sweaty fingers.
The SteelSeries Rival 300 really has a solid build to it. There is no rattling internally nor from the mouse left/right buttons, even when shaking the mouse vigorously.
The back arch angle of the Rival 300 has a medium to high arch so it's great for palm and claw grippers. The back of the mouse measures 70mm across while the front section of the Rival 300 mouse measures around 50mm. The Rival 300 measures 130mm long.
You can change the color of the scroller and the SteelSeries logo on the arch of the mouse by using SteelSeries Engine 3 Software.
The Engine 3 software allows you to adjust the CPI (all the way from 50 to 6500 in increments of 50), as well as change button configuration to keyboard, macros and media buttons. Check out the review of the Sensei Ten mouse.
