The Razer DeathAdder V4 Pro is a right-handed wireless gaming mouse built around Razer's Focus Pro 45K Gen-2 sensor, offering a maximum resolution of 45000 DPI with a minimum starting point of 100 DPI for precise, user-defined sensitivity. It connects via 2.4GHz wireless or USB, weighs just 63 g, and supports use while charging, making it a practical option for extended sessions without interruption.

On the performance side, the DeathAdder V4 Pro reaches a polling rate of 8000 Hz, a maximum tracking speed of 900 IPS, and a peak acceleration of 85G. It features six fully programmable buttons — including two side buttons, a DPI switching button, and a profile switching button — with one onboard memory profile available for storing configurations. The mouse measures 128 mm in height, 68 mm in width, and 44 mm in thickness, includes extra weights for balance adjustment, and is backed by a two-year warranty.

Pros

The 8000 Hz polling rate ensures highly responsive cursor tracking, well above standard polling rates for gaming mice
A DPI range spanning from 100 to 45000 DPI with full adjustability allows precise sensitivity tuning for a wide variety of tasks
All 6 buttons are fully programmable, offering extensive layout customization without needing additional hardware
A rated battery life of 150 hours on a single charge reduces how often the mouse needs to be plugged in
The mouse can continue to be used while charging, preventing downtime during low-battery situations
Extra weights are included, giving users the option to increase the feel and balance of the mouse to their preference

Cons

Designed only for right-handed users, making it unsuitable for left-handed users
No wireless charging support means the mouse must be connected via cable to recharge
Only one onboard memory profile is available, limiting how many configurations can be stored directly on the device
The absence of RGB lighting may be a drawback for users who prefer customizable visual feedback or aesthetic options
No tilting or thumb scroll wheel is included, which restricts navigation options for users who rely on those features

Who is this for?

This mouse is well-suited for right-handed users who prioritize precise, responsive tracking, particularly those engaged in fast-paced gaming where the 8000 Hz polling rate and wide DPI range from 100 to 45000 DPI provide a clear advantage. The 150-hour battery life and ability to continue using the mouse while charging make it a practical choice for users who need extended, uninterrupted sessions. Those who prefer a customizable physical feel will also benefit from the included extra weights, and users who want full control over their input layout will appreciate having all 6 buttons programmable.

Who is this NOT for?

Left-handed users will find this mouse entirely unsuitable, as its ergonomic shape is designed exclusively for right-handed use. Users who prefer a more feature-rich scroll experience will be limited by the absence of both a tilting and a thumb scroll wheel, making it a poor fit for workflows that rely on horizontal scrolling or multi-directional navigation. Additionally, those who need to store multiple device configurations on the hardware itself may find the single onboard memory profile restrictive, and users who expect wireless charging convenience will need to rely on a physical cable connection to recharge.
