The Razer Viper Ultimate is ideal for first-person shooter games. The click latency is extremely low, whether wired or wireless, and even competitive gamers will not notice any delays in-game. It’s also relatively light, with excellent sensor performance. Its shape lends itself well to a fingertip grip for nearly all hand sizes, but larger hands may struggle with a palm or claw grip. The Viper Ultimate’s overall design philosophy is reminiscent of classic Razer mice, but with less curvature, allowing for ambidextrous play. Another nod to left-handed users is the presence of two buttons on either side.
It has a matte black finish and rubberized sides for a firm, comfortable grip. The only RGB lighting zone is the illuminated Razer symbol near the back of the mouse, making the Viper Ultimate a more understated product in terms of bling. The Viper Ultimate, like the Basilisk Ultimate, has a compartment on the bottom of the mouse that houses the USB Type-A dongle for connecting to your computer. When not in use, you can charge the mouse using the included RGB charging dock or the detachable MicroUSB to USB Type-A cable.
[content-egg-block template=offers_logo hide=price]To accommodate the Viper Ultimate’s small form factor, some compromises were required. Unlike many other gaming mice, the CPI switch is located on the underside of the mouse rather than directly beneath the scroll wheel. While this prevents accidental clicks, it also means that on-the-fly CPI adjustment is not possible.
The Viper Ultimate stands only 1.49 inches (37.8mm) tall, which may pose a problem for gamers with larger hands who prefer a palm grip. With so little real estate to cling to, the ring and pinky fingers naturally rest in a position that allows for far too many accidental clicks. The Viper Ultimate is ideal for users with smaller hands who prefer a claw grip.
The Viper Ultimate is an extremely light mouse, weighing only 0.16 pounds (74g). Depending on who you are, this can be a blessing or a curse. If you prefer a heavier mouse, like me, you’ll find yourself frequently over or under correcting because the lack of heft introduces momentum. However, eSports pros who rely on motion economy will most likely have a better experience.
