This mouse was replaced by the Razer Viper V3 Pro

The Razer Viper V2 Pro is an ultra-lightweight, wireless gaming mouse that continues Razer's popular Viper lineup. It has the same symmetrical shape but incorporates major design changes and improvements over the Razer Viper Ultimate. Razer has significantly reduced the weight of this mouse; however, they've accomplished this in part by removing several features of the previous generations, including side grips, RGB lighting, and ambidextrous controls. Besides weight changes, this mouse also has a new Razer Focus Pro 30K sensor and uses a new generation of optical switches. Razer also indicates they've improved battery life and wireless performance.

Note: We've received feedback from users reporting that they have received this mouse with a defective wireless receiver. We've included more details about this issue in the Wireless Versatility section below.

Our Verdict

7.2 Work

Though not specifically for this use, the Razer Viper V2 Pro is decent for office and multimedia use. It connects wirelessly with its USB receiver, and you can reprogram buttons to perform productivity actions and macros using the customization software. Unfortunately, there's no Bluetooth support. Also, the scroll wheel lacks a free-scrolling mode and left/right tilt inputs for horizontal scrolling.

Pros
  • Comfortable symmetrical shape.
  • Build quality feels excellent.
Cons
  • Scroll wheel lacks left-right inputs and a free-scrolling mode.
  • Lacks a storage compartment for its wireless receiver.
  • Somewhat bulky; isn't designed to be stored in laptop bags or cases.
9.3 Video Games (FPS)

The Razer Viper V2 Pro is a remarkable FPS gaming mouse. It's extremely lightweight and feels very sturdy.

Differences Between Sizes And Variants

The Razer Viper V2 Pro we tested is the matte black color variant. It's also available in matte white. You can see the label for our unit here.

Compared To Other Mice

The Razer Viper V2 Pro is a continuation of Razer's popular Viper lineup. It features several improvements, including a brand new sensor, a new generation of optical switches, and a significantly lighter weight than their previous flagship model, the Razer Viper Ultimate. However, this weight saving comes at the cost of several features that characterized earlier generations of this mouse, including the RGB lighting, rubberized side grips, and an optional charging dock. This mouse only has a pair of side buttons on the left, while the Razer Viper Ultimate and Razer Viper 8KHz featured buttons on either side, making them popular options for left-handed users. Overall, this mouse is a high-performance option that competes directly with similar flagship models like the Logitech G PRO X SUPERLIGHT. However, given its reduced feature set and premium price point, it won't be a perfect fit for everyone.

The Razer Viper V2 Pro has outstanding sensor latency performance. It reacts incredibly quickly to your inputs, and you won't notice any lag or delay. We conducted this test at the maximum native polling rate of 1000Hz.

We also tested this mouse at 8000Hz using Razer's HyperPolling Dongle, which they sell separately. We found that the delay to start of movement and the delay at half movement were slightly better at 12.9ms and 2.9ms, respectively. However, the delay to end of movement was slightly worse at 6.0ms, which we didn't expect. We reran this test multiple times to confirm and still got the same results. Here is a screenshot of our results, and here is the video.

In addition to the standard sensor adjustment settings found on most gaming mice, this mouse also has a setting called "Asymmetric Cut-Off," which lets you independently configure the lift-off and landing distance to suit your playstyle.

The available polling rate settings on the Razer Viper V2 Pro are 125Hz, 500Hz, and 1000Hz. Razer also offers a separate "HyperPolling" receiver available as a separate purchase on their website. This additional receiver allows you to increase the polling rate up to 8000Hz. However, these tests were conducted without this receiver, using a polling rate setting of 1000Hz.

If you're interested in a gaming mouse that supports a higher wireless maximum polling rate out of the box, check out the Logitech G PRO X SUPERLIGHT 2 or the Razer Viper Mini Signature Edition.

Overall, Razer's Synapse software is very good. It's well laid out and fairly easy to use. You can adjust settings like CPI, lift-off distance, surface calibration, profile calibration, and power settings. However, like many software options from other major manufacturers, this software is criticized for requiring frequent updates and taking up disproportionate system resources. You may find this software frustrating if you prefer more lightweight software options or no software at all.

If you'd prefer a high-performance wireless gaming mouse that doesn't use software but instead allows you to configure settings using buttons directly on the mouse, check out the Vaxee XE Wireless or the BenQ ZOWIE U2.
