Tom’s Hardware’s review describes the Razer Basilisk V4 Pro as a comfortable, versatile gaming mouse with a lighter design, updated sensor and switches, and up to 200 hours of battery life. Its AI prompt button disrupts the thumb-button layout, while the mouse’s price and relatively large shape may put off some buyers.

Tom’s Hardware has reviewed Razer’s Basilisk V4 Pro, a refreshed all-around gaming mouse with a Focus Pro 50K optical sensor, fourth-generation optical switches and a dedicated AI prompt button. The review says it feels good and is lighter than the Basilisk V3 Pro, but flags the new button’s effect on the thumb controls, the mouse’s price and its large size as drawbacks.

The Basilisk V4 Pro carries forward the line’s contoured, right-handed shape, extra buttons and RGB lighting. It is aimed at players looking for more functionality than a stripped-down FPS mouse, rather than a minimal design focused solely on competitive performance. Tom’s Hardware characterizes it as a versatile option for gamers who want additional controls without a button-heavy layout.

Razer lists a Focus Pro 50K optical sensor, fourth-generation optical mouse switches and a maximum 8,000 Hz polling rate among the mouse’s hardware features. It supports multiple forms of connectivity. Battery life is rated at up to 200 hours over 2.4GHz at 1,000 Hz; the review lists about 54 hours at 8,000 Hz. The higher polling rate is associated with substantially shorter battery life.

Tom’s Hardware’s verdict is positive on the mouse’s feel and its lighter weight compared with the V3 Pro, while its reservations focus on practical trade-offs. The reviewer says the AI prompt button disrupts the harmony of the thumb buttons, and also identifies the price and relatively large body as reasons to hesitate. The supplied review details do not state a price, so the cost cannot be quantified here.

A More Feature-Rich Basilisk

The review matters to shoppers comparing versatile gaming mice: the Basilisk V4 Pro adds current sensor and switch specifications while retaining the larger, contoured form and extra controls that distinguish the line from lighter, simpler FPS designs. Its listed battery life also varies sharply by polling setting, a consideration for buyers weighing responsiveness against how often they want to recharge.

The AI prompt button is a design choice rather than evidence of a particular performance improvement. Tom’s Hardware’s main criticism is that it interrupts the existing thumb-control arrangement. That makes the review useful for buyers who care about button placement as much as headline specifications. The review does not provide test results establishing a broader benefit from the AI feature.

The Basilisk Line’s Latest Refresh

Razer has been updating its gaming mouse lineup over the past two years, according to Tom’s Hardware. The review describes the Basilisk V3 Pro 35K, released in October 2024, as a sensor update to the V3 Pro rather than a wider redesign. The V4 Pro is presented as a more substantial update to the line.

The broader Basilisk identity remains in place: a right-handed ergonomic shape, RGB lighting and several extra buttons. Tom’s Hardware contrasts that all-rounder approach with mice built for players prioritizing competitive performance above other uses. The V4 Pro’s specifications advance the hardware, but the review’s assessment turns on whether its added features and controls suit a buyer’s preferences.

“A great all-around gaming mouse for gamers who want more functionality than a stripped-down FPS mouse, but who aren’t totally button-crazy.”

Price and AI Use Details

The provided review details do not give the Basilisk V4 Pro’s price, its release date or a precise description of what the AI prompt button does, which applications it works with, or whether it can be customized. The review’s criticism addresses its effect on the thumb-button layout, not a measured result for AI performance.

The stated battery figures are tied to particular wireless and polling conditions: up to 200 hours at 1,000 Hz over 2.4GHz, and roughly 54 hours at 8,000 Hz. The supplied information does not detail the testing method or battery life under other settings. Buyers should not treat either figure as a guarantee for every use pattern.

Buyer Checks Before Choosing

Anyone considering the mouse should compare its price with other gaming mice, check whether its large, right-handed shape fits their grip, and decide whether the added controls suit their games. The AI button’s utility will depend on its supported functions and how well those fit a buyer’s software and habits; those details are not established in the review information provided here.

For battery expectations, buyers should also compare polling-rate settings with their priorities. The review’s figures indicate a substantial difference between the stated 1,000 Hz and 8,000 Hz operating conditions. No follow-up product update or additional review findings are specified.
