Tom’s Hardware’s review finds the Razer Basilisk V4 Pro to be a comfortable, versatile gaming mouse that is lighter than its predecessor and rated for up to 200 hours of battery life at 1,000 Hz over 2.4GHz wireless. Its AI prompt button disrupts the thumb-button layout, while the high price and relatively large size may put off some buyers.
Razer’s Basilisk V4 Pro keeps the right-handed, feature-rich design of its predecessor while adding a Focus Pro 50K sensor, updated optical switches and a dedicated AI prompt button. In its review, Tom’s Hardware describes it as a comfortable, versatile gaming mouse with long battery life, but says the AI button disrupts the thumb controls and the mouse is expensive and somewhat large.
The Basilisk V4 Pro is aimed at players who want more controls than a stripped-down FPS mouse without opting for a device crowded with buttons. It retains the Basilisk family’s contoured, right-handed shape, extra controls and RGB lighting. Tom’s Hardware’s review says the updated mouse is lighter than the V3 Pro and feels good to use, though it remains a little large.
Razer lists a Focus Pro 50K optical sensor, fourth-generation optical mouse switches and a maximum polling rate of 8,000 Hz. The review material also gives a battery rating of up to 200 hours over 2.4GHz wireless at 1,000 Hz, falling to 54 hours at 8,000 Hz. Those figures are stated specifications; the supplied review details do not describe a separate battery-life test or its conditions.
The most conspicuous design change is the AI prompt button, which Tom’s Hardware says upsets the otherwise harmonious arrangement of the thumb buttons. The review’s overall assessment is positive for users seeking a do-it-all gaming mouse, but flags that the added feature comes with trade-offs in price, size and button layout.

Razer Basilisk V4 Pro: How AI Changes a Tried-and-True Mouse
A familiar, feature-rich gaming mouse gets a sensor refresh and a dedicated AI prompt button. Tom’s Hardware likes its comfort and versatility, while questioning the button placement and the trade-offs in size and price.
A familiar all-rounder, with a new point of friction
The V4 Pro keeps the Basilisk’s contoured, right-handed shape, extra controls and RGB lighting while bringing updated internal hardware.
Comfort & versatility
The review describes a comfortable mouse suited to players who want more controls than a stripped-down FPS design.
Lighter, updated hardware
It is lighter than the V3 Pro and adds a Focus Pro 50K sensor plus fourth-generation optical mouse switches.
AI button disrupts the flow
Tom’s Hardware says the dedicated prompt button upsets the otherwise harmonious arrangement of thumb controls.
Polling speed changes the stated runtime
Razer’s listed figures show a shorter rated battery life at the maximum polling rate.
Nearly four times the rated hours at 1,000 Hz
The 200-hour estimate applies to 2.4GHz wireless at 1,000 Hz; the stated figure at 8,000 Hz is 54 hours.
Rated estimates, not independently verified test results in the supplied review details. Conditions beyond the stated wireless connection and polling rate are not provided.
An incremental update with a broader control story
The Basilisk line is positioned as a feature-rich all-rounder rather than a minimal esports mouse.
| Area | Basilisk V4 Pro | What the review says |
|---|---|---|
| Shape & feel | Retained, lighter | Right-handed contoured form; comfortable to use, though still somewhat large. |
| Sensor & switches | Focus Pro 50K · Gen 4 optical | Updated sensor and fourth-generation optical mouse switches. |
| Polling & battery | Up to 8,000 Hz | Rated up to 200 hours at 1,000 Hz, or 54 hours at 8,000 Hz over 2.4GHz wireless. |
| AI control | Dedicated prompt button | Its placement disrupts thumb-button arrangement; service, setup and configuration details are not supplied. |
| Buyer trade-offs | Price · size · layout | The review flags high cost, a relatively large body and the changed thumb-control layout. |
A physical shortcut, with its purpose still unclear
The supplied review details do not identify the AI service or explain what the button does in daily use.
Familiar layout
The Basilisk’s thumb area is built around extra, programmable controls.
New prompt button
A dedicated physical control is added to the established design.
Control-space cost
The review says its position disrupts the otherwise harmonious thumb layout.
Value unanswered
Its usefulness and configuration options are not established in the supplied details.
Who may find the V4 Pro a fit?
The review frames the decision as a choice between a versatile control set and a simpler, smaller or lower-cost mouse.
Could suit
- Players who value a comfortable, general-purpose gaming mouse.
- Users who want extra controls, lighting and multiple connectivity options.
- Buyers who are comfortable with a larger shape and premium positioning.
Consider carefully
- Shoppers seeking a compact, lightweight or lower-cost option.
- Players who prefer a clean, minimal thumb-button arrangement.
- Anyone choosing primarily for the AI feature before its function and setup are clear.
Context: Tom’s Hardware says the preceding Basilisk V3 Pro 35K launched in October 2024 and was essentially the V3 Pro with a new sensor. The supplied material does not provide the V4 Pro’s price, release date, full test results or a further review milestone. Check current availability, pricing and Razer’s feature documentation before buying.
A Familiar Mouse Adds an AI Control
The Basilisk V4 Pro illustrates how gaming peripherals are adding features beyond sensor performance and conventional programmable controls. Here, the AI prompt button is a physical addition to a familiar mouse design, but the review raises a practical question: whether a new shortcut is useful enough to justify the space it occupies in a control layout.
For buyers, the review points to a choice between versatility and simplicity. The sensor, polling rate and multiple connectivity options are aimed at users who want a capable general-purpose gaming mouse, while the price and larger shape may matter more to shoppers seeking a lightweight, compact or lower-cost option. The AI feature’s real value is not established by the supplied review details.

The Basilisk’s Incremental Update
Razer has refreshed its gaming mouse lineup over the past two years, according to Tom’s Hardware. The previous Basilisk model mentioned in the review is the Basilisk V3 Pro 35K, released in October 2024. The review describes that version as essentially the V3 Pro with a new sensor, making the V4 Pro a broader update to the line.
The Basilisk range is positioned as an all-rounder, rather than a mouse designed primarily for esports players chasing the highest performance or the fewest possible controls. The V4 Pro carries that approach forward with a familiar shape, extra buttons and lighting, alongside refreshed internal specifications and the AI prompt control.

The supplied review details do not explain which AI service or function the button invokes, how it is configured, or whether its behavior can be changed. They also do not establish how useful the feature is in everyday gaming or other tasks. Without those details, the button’s practical value is difficult to weigh against its effect on thumb-button placement.
The material also does not give the mouse’s price, a release date, or full test results for performance and battery life. The stated battery figures should be read as rated estimates, not as independently verified results in the review information provided here.

Buyer Decisions Await More Detail
Readers comparing gaming mice can weigh the review’s stated strengths—comfort, a lighter build and long rated battery life—against its concerns about cost, size and the AI button’s placement. A firmer judgment on that AI feature will depend on details about what it does and how users can configure it.
The supplied information does not identify a further review milestone, software update or launch event. Prospective buyers should check current availability, pricing and Razer’s feature documentation before deciding whether the V4 Pro’s added controls suit their setup.
