Razer’s new wireless mouse offers a lightweight, tasteful look

If you prefer a mouse that glides over a mouse pad with minimal effort, or in this case a glass surface, finding a lightweight, wireless mouse is a good move. Lightweight mice are often LED-laden or hole-riddled pieces that look odd in most environments outside of a gaming lair. But Razer’s Viper V2 Pro Announced Tuesday is a 2.05-ounce (58 g) wireless mouse with a muted look that’s suitable for more traditional-looking setups.

Razer is best known for flashy, snake-clad PCs and gamer peripherals. The Viper 2 Pro, with an optical sensor that supports adjustable DPI (dots per inch, see more in our PC Mouse Terms article) of up to 30,000 and extreme features such as adjustable take-off distance, is also intended for PC gamers. But with its muted black or tasteful white design and symmetrical shape, you might not notice it at first. Though spotting the angle lines below the left and right and the more subtle three-headed snake might provide clues.

Still, there’s no RGB logo, and that took 0.1 ounce (2.7 g) off the mouse’s weight compared to its predecessor, the 2.61-ounce (74 g) Razer Viper Ultimateand also helps extend battery life. The only real color accent is the light south of the scroll wheel, which indicates which DPI setting you’re currently using.

Razer has also saved some weight by going from a rigid circuit board to a rigid one and changing the primary click buttons. In addition, the mouse uses a battery that Razer claims is lighter and more efficient, making it 0.09 ounces (2.6 g) lighter than the Viper Ultimate and delivering 80 hours instead of 70 hours of battery life.

The new mouse has a maximum speed and acceleration of 750 IPS and 70 g respectively, compared to 650 IPS and 50 g on the Viper Ultimate.

The new mouse also doesn’t have integrated side grips like the previous model. The grips shave 0.13 ounces (3.7 g) off the mouse and offer more options. For example, you can choose to use Razer’s sold separately grip tape on one side of the mouse or add a rubbery texture to the primary buttons.

However, grip tape can wear off and leave a sticky mess. And if your hands tend to get clammy when you move the mouse around, losing the built-in side grips could be a downgrade.

Another downside: The look of the black tape on the mouse's white livery is polarizing.

The Viper V2 Pro only has two side buttons (both on the left), while the Viper Ultimate has four (two on each side). Fewer side buttons save the Pro 0.1 ounces (2.9 g), but keep it from being ambidextrous. That’s a shame, given the disappointingly small number of left-handed wireless mice available.

But with side buttons on both sides of the mouse, all the side buttons can be difficult to use. One solution is to remove the side buttons by the user, such as the Logitech G Pro Wireless† But Razer takes neither route, flatly calling this a right-handed mouse.

Razer made a more obvious good move by upgrading to USB-C charging. The Viper V2 Pro also uses a 2.4GHz wireless USB-A dongle. The lack of Bluetooth can be a deal-breaker for office workers who have few ports or have moved to one of the many ultra-light laptops that don’t have USB-A.

For those looking for a wireless mouse with extreme gaming specs and those looking for a rechargeable mouse for work that’s more advanced than it looks, the $150 Viper V2 Pro is an intriguing option.
