Razer Basilisk V4 Pro Costs $169.99 for 200-Hour Battery
The new mouse adds an AI key and cuts weight to 100 grams, but the button layout forces users to compromise on thumb placement.

Razer updated its Basilisk gaming mouse line for the first time since October 2024, introducing the Basilisk V4 Pro.
The new device is priced at $169.99 in black and white versions. It launched alongside the Mouse Dock V2 Pro, which sells separately for $69.99.
The Basilisk V4 Pro features a Focus Pro 50K optical sensor capable of 50,000 DPI and 930 IPS tracking. It includes fourth-generation optical switches rated for more than 100 million clicks. Connectivity options include 2.4GHz wireless, Bluetooth, and USB-C.
Senior editor Sarah Jacobsson Purewal of Tom's Hardware reviewed the device. She recommended it for players seeking more functionality than a stripped-down shooter mouse but fewer buttons than a complex design. The review noted the mouse is not ideal for top-level competitive play.
The mouse weighs 3.53 ounces, or 100 grams. This is nearly half an ounce lighter than the previous V3 Pro 35K model, which weighed 3.95 ounces. The reduction makes the device easier to pick up, though it remains far from ultralight.
The primary design change is the addition of two buttons, bringing the total to 12 programmable inputs. A new button beside the left mouse button switches profiles. A third thumb button sits in front of the existing cluster and opens Razer's AI prompt by default.
The reviewer found the new layout awkward. The mouse measures 5.02 inches long. The profile button sits at the front edge, placing it too far from the thumb for comfortable use with medium-sized hands. The new AI button is the same size as the other thumb buttons, pushing the existing cluster back. This leaves the first thumb button, MB4, difficult to reach. The reviewer stated that all three thumb buttons felt slightly off despite remapping options.
Battery life increased from 150 hours on the previous model to 200 hours at 1,000 Hz polling over 2.4GHz wireless. At the maximum 8,000 Hz polling rate, battery life drops to 54 hours. The box includes a USB-A dongle, an adapter, and a 6-foot braided cable. It does not include grip tape or a flexible HyperFlex cable.
