The new Razer Basilisk V4 Pro positions itself firmly in premium technology territory, retailing at $169.99. Reviewers and surrounding coverage have focused heavily on its ergonomic design and high-level specifications.
Weight and shape define the initial user experience. The mouse weighs 100 grams, placing it outside the trend of ultralight devices. Razer has not attempted to mask this weight. The weight, the company argues, contributes to stability and a substantial shape designed to fill the hand.
The design maintains the familiar Basilisk silhouette: a right-handed ergonomic form featuring a contoured thumb rest and a slightly rearward hump. Publications describing it as a “meaty mouse” note that the hand falls naturally into place. While the sculpted shape offers comfort for long sessions, reviewers caution that it may not be suited for smaller hands.
Performance hardware is exceptional. Internally, the Basilisk V4 Pro uses the Focus Pro 50K Optical Sensor Gen-3. This sensor offers 50,000 DPI maximum, 930 inches per second tracking speed, and 90G acceleration. This is paired with fourth-generation Razer optical mouse switches.
Achieving connectivity versatility, the mouse supports polling rates up to a true 8,000Hz over both wired and wireless links. These are flagship numbers, putting the V4 Pro in the same high-performance conversation as Razer’s Viper line.
The device offers multiple connection options, including HyperSpeed 2.4GHz, Bluetooth 6.2, and wired USB-C. Unusually for a dedicated gaming peripheral, Razer implemented five-device pairing support.
Powering this versatility is the HyperScroll wheel, which features second-generation design elements, including free-spin and tactile modes, along with horizontal scrolling. This wheel contributes to the mouse’s appeal among productivity users as well as gamers.
At its core, the V4 Pro features 14 customizable inputs. Functionality is enhanced by dedicated keys such as a Hypershift clutch, an AI Prompt Master button, and a Perfect 180 button designed for instantaneous camera spins. The inclusion of both the AI key and the button count has resulted in mixed reactions from the tech community.
Battery life projections are specific to use case. At the competitive 8,000Hz polling rate, the mouse provides 54 hours of runtime. If polled at 1,000Hz over HyperSpeed Wireless Gen-2, battery life extends to 200 hours. Bluetooth operation offers up to 275 hours with polling turned down.
Ultimately, the Basilisk V4 Pro is designed as a single, do-everything device. The combination of robust gaming specs and a focus on productivity controls suggests it targets the user who prioritizes comfort and feature density over minimal weight. Though the Perfect 180 button has prompted debate about competitive fairness, the overall consensus positions the V4 Pro as one of the most comfortable right-handed gaming mice available to those with larger hands.
