Razer Basilisk V4 Pro costs $169.99 with 200-hour battery
The new mouse adds an AI key and extends battery life, though reviewers note the button layout compromises thumb comfort.

Razer has updated its Basilisk mouse line for the first time in two years.
The new Basilisk V4 Pro costs $169.99 in both black and white finishes. It launches alongside the Mouse Dock V2 Pro, which is available separately for $69.99.
The device features a new AI button and a longer battery life. It includes 12 programmable buttons, up from 10 on the previous model. One new button sits beside the left clicker to switch profiles. A third thumb button opens Razer's AI prompt by default.
Reviewers say the button placement creates ergonomic issues. The mouse is 5.02 inches long. This length pushes the profile button to the front edge, making it difficult to reach for users with medium-sized hands. The AI button is the same size as the other thumb controls. It pushes the existing thumb cluster backward. This makes the first thumb button, labeled MB4, hard to press comfortably.
Sarah Jacobsson Purewal, a senior editor at Tom's Hardware, noted that all three thumb buttons felt slightly off in testing. She questioned whether every mouse needs a dedicated AI prompt button. The review also highlighted that the profile button is too far forward for comfortable use.
The hardware specifications remain competitive. The mouse uses the Focus Pro 50K optical sensor, which reaches 50,000 DPI and 930 IPS. It tracks on most surfaces, including glass at least 4mm thick. The fourth-generation switches are rated for more than 100 million clicks. Testing showed no misclicks or double-clicks. The black version weighs 3.53 ounces. This is 0.42 ounces lighter than the Basilisk V3 Pro 35K, which weighed 3.95 ounces.
Battery life has increased to 200 hours at 1,000 Hz polling over 2.4GHz wireless. At the maximum polling rate of 8,000 Hz, the battery lasts 54 hours. The previous model offered 150 hours at 1,000 Hz. The mouse connects via 2.4GHz wireless, Bluetooth, or USB-C. The box includes a USB-A dongle, an adapter, and a 6-foot braided cable. It does not include a HyperFlex cable or grip tape.
The tilt wheel offers two tactile modes with 24 and 48 steps, plus a free-spin mode. Reviewers found the free-spin setting too sensitive and prone to backscrolling. The precision tactile mode received praise. The Mouse Dock V2 Pro includes an integrated 8,000 Hz receiver and eight RGB zones. It also supports several older Razer mice.
