Razer Viper V4 Pro Gaming Mouse Leaks in Physical and Online Stores

Leaks about an upcoming Razer Viper V4 Pro have been circulating for a while now, with multiple e-sports pros seemingly using the new mouse in competitive tournaments. Now, though, the new wireless mouse has effectively been confirmed by two separate posts showing off early retail appearances of the Viper V4 Pro. First, a Reddit user posted in-store images of the Viper V4 Pro retail packaging that had seemingly accidentally been put in the storefront ahead of launch, and although the post was subsequently deleted by the r/MouseReview subreddit user, it didn’t stop the images from showing up on X. For the most part, it seems like an iterative update to the existing Viper V3 Pro, as was expected, given the specs of the DeathAdder V4 Pro.

The aforementioned retail box gives us a good idea of what to expect from the Viper V4 Pro—that is, a minor sensor update to the Razer Focus Pro 50K, new Razer Optical Gen 4 switches, a Razer optical scroll wheel, and a 49 g total weight. Notably, the sensor is a slight improvement over even the Razer DeathAdder V4 Pro, although much of the rest of the mouse’s specifications are practically identical. As expected, the Viper V4 Pro adopts the same more efficient dome-shaped wireless receiver as the DeathAdder V4 Pro, replete 8K polling and a claimed 180-hour battery life. According to Danish computer store, ComputerSalg, where the Viper V4 Pro was prematurely launched as well, although without any photos, the mouse will also be available in white at launch, and it will cost a staggering $199 (DKK 1,290 converted excluding VAT). This is significantly more expensive than both the existing Viper V3 Pro and the DeathAdder V4 Pro, so it’s likely a pre-launch placeholder or the price of some special edition colorway. All of this indicates that the Viper V4 Pro is likely to launch within the next few weeks, but it will have to contend with both the new tech in the Logitech G Pro X2 Superstrike and the slew of Chinese gaming mice with similar hardware specs and much lower pricing.
