Test Results
The Razer Viper V2 Pro looks very similar to previous versions of this mouse with a fairly subdued aesthetic with some aggressive angles. It's made of matte black textured plastic and has glossy black plastic accents. There's a very small LED light behind the scroll wheel that indicates what CPI setting you're using. There's also a Razer logo on the palm rest, but unlike previous generations, there isn't any RGB lighting. If you're interested in a lightweight gaming mouse that's available in a range of more expressive colorways, check out the LAMZU Atlantis.
The Razer Viper V2 Pro feels very sturdy and well-built, despite being much lighter than previous versions. There aren't any rattling sounds if you shake the mouse and no wobble in the buttons or scroll wheel. That said, you can register side button clicks by squeezing forcefully enough into the side of the mouse, but this isn't an issue during regular use.
Razer indicates that the white color variant of this mouse is approximately one gram heavier. If you're interested in an even lighter wireless gaming mouse, you may be interested in the Finalmouse Starlight Pro - TenZ Medium or the substantially lighter Zaunkoenig M2K. However, both these mice are only available from third-party retailers at this point and tend to be quite expensive.
Overall, the Razer Viper V2 Pro has a very comfortable symmetrical shape. It's also low-profile and has a fairly subdued hump towards the middle. The buttons are also well-placed, and the entire plastic body is slightly textured for added grip. Unlike most models in the Viper lineup that are true ambidextrous mice with a pair of buttons on both sides, this mouse only has buttons on the left. This mouse also lacks the rubber side grips found on the previous generation Razer Viper Ultimate, though it comes with a set of adhesive grips.
If you're looking for a mouse with a true ambidextrous design with customizable side buttons on both sides, see our review for the Logitech G PRO 2 LIGHTSPEED.
For an alternative option that's just as lightweight but has an ergonomic, right-handed shape, check out the Pulsar Xlite V2 or the Razer DeathAdder V3 Pro.

The Razer Viper V2 Pro has exceptionally low and very consistent click latency. It delivers an extremely responsive-feeling experience for gaming in any genre and is well-suited for casual and competitive play.
We also tested this mouse at 8000Hz using Razer's HyperPolling Dongle, which they sell separately. We found the click latency to be even better at a remarkable 1.2ms. Here is the graph of our results, and here is the video.
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.
The mouse wheel feels precise and has well-defined steps. It also has a rubberized texture for grip and operates quietly, even at high speeds.
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.
