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
Though not specifically for this use, the Razer Viper V2 Pro is excellent 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.

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.

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. For an alternative option that's just as lightweight but has an ergonomic, right-handed shape, check out the Pulsar Xlite v2 Wireless or the Razer DeathAdder V3 Pro.
Razer advertises that the Razer Viper V2 Pro has a battery life of up to 80 hours. This mouse doesn't support Bluetooth but. Check out the ASUS ROG Harpe Ace Aim Lab Edition if you want a high-performance wireless gaming mouse with Bluetooth support.
Note: We've received feedback from several community members and found other reports online that the wireless receiver included with the Razer Viper V2 Pro can arrive defective. For some users, the receiver functions for a short time out of the box but then stops working. While this issue seems to affect a relatively small number of people, we're keeping an eye on the situation and will update this review with any developments. We also encourage you to make sure you're purchasing this mouse directly with Razer or one of Razer's authorized sellers. If you've purchased this mouse and found it has a defective receiver, we encourage you to reach out directly to Razer's customer support, as they have typically been quick about replacing defective receivers in these cases. If you've purchased this mouse and found it has a defective receiver, we encourage you to reach out to us with your experience in the forum section at the end of this article.

You can reprogram nearly all buttons on the Razer Viper V2 Pro to perform a variety of actions, including profile switching, multimedia controls, windows shortcuts, and keyboard functions. You can also set a Hypershift button which enables a second layer of button assignments. There's an additional button on the bottom of the mouse that isn't programmable. This button toggles the power when held for three seconds and cycles through five customizable CPI settings when pressed and released. The left- and right-click buttons use Razer's new Gen-3 optical switches, rated for 90 million clicks.
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.
The available polling rate settings on the Razer Viper V2 Pro are 125Hz, 500Hz, and 1000Hz. 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 both the lift-off and landing distance to suit your playstyle. Note that the sensor on this mouse can track on glass surfaces, which is rare for recent mouse releases with optical sensors.
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.
