The Razer BlackWidow series has long been a cornerstone in the world of gaming keyboards, known for its reliability, precision, and distinct mechanical feel. Over the years, Razer has refined the design and technology behind each iteration, pushing the limits of what a performance keyboard can deliver. The latest addition, the BlackWidow V4 Low-Profile, takes this legacy in a new direction with a slimmer, sleeker form that redefines comfort and speed.
This new low-profile model is more than just a cosmetic refresh. It brings together Razer’s renowned switch technology and premium materials in a streamlined chassis designed for both gaming and productivity. The reduced height not only modernises the look but also enhances ergonomics, creating a setup that feels natural for long hours of use without sacrificing responsiveness or control.
After extensive testing across a mix of gaming titles and daily tasks, it’s clear that Razer has struck a fine balance between performance and practicality. The BlackWidow V4 Low-Profile isn’t simply a thinner version of its predecessors—it’s a thoughtfully engineered keyboard that embraces innovation while staying true to the qualities that made the original series a classic.
Design and Functionality
Razer’s focus on refinement is immediately apparent the moment you set eyes on the BlackWidow V4 Low-Profile. The ultra-slim design sits low on the desk, with a front height of just 18.5mm, giving it a modern, minimalist presence that complements any gaming or work setup. The reduced height encourages a more neutral wrist position, helping to minimise fatigue during long hours of use.
The keyboard’s frame is constructed from 5052 aluminium alloy, chosen for its impressive strength-to-weight ratio. It feels incredibly solid without being overly heavy, giving it that premium heft gamers expect from a flagship model. Combined with an ABS plastic underside, the build strikes a perfect balance between rigidity and portability.
Every surface detail has been carefully considered. The brushed aluminium top gives off a refined sheen, while the subtle edges and rounded corners create a clean, professional silhouette. It’s the type of keyboard that blends effortlessly into a home office or a high-end gaming rig.
Razer’s low-profile mechanical switches are at the heart of this model, available in clicky, tactile, and linear variants. Each switch delivers a distinct typing feel, catering to different preferences—whether you crave a crisp click, a soft bump, or a smooth, fast actuation. They’re engineered for speed and precision, providing the responsiveness competitive players demand.
The Yellow Linear switches in particular offer a short 1.2mm actuation distance and a total travel of 2.8mm. This translates to lightning-fast keystrokes with minimal resistance, ideal for players who thrive on rapid reactions. Despite their classification as linear, they still retain a subtle tactile quality that feels satisfying for both typing and gaming.
To complement the mechanical excellence, Razer has layered in sound-dampening foam beneath a stainless steel top plate. This dual-layer system softens the keystroke acoustics, producing a deep, muted sound rather than the typical sharp mechanical clack. It’s perfect for shared spaces where quieter operation is appreciated.
The overall typing experience benefits further from pre-lubricated stabilisers that eliminate rattles from larger keys such as the spacebar and enter key. This attention to detail enhances consistency across the board, ensuring each press feels smooth and stable.
A standout visual feature is the circular stem wall on each switch, designed to optimise light transmission. Combined with Razer’s doubleshot PBT keycaps, the RGB backlighting shines evenly and vividly across the board. The legends remain sharp and easy to read, even under bright lighting conditions.
The keyboard’s compact Tenkeyless (TKL) option adds versatility for gamers who prefer more mouse room or a cleaner setup. Despite its smaller footprint, it retains the same robust materials and premium build as the full-size version. Both layouts maintain that familiar Razer aesthetic—sleek, purposeful, and unmistakably high-end.
Connectivity is another strong point, with support for Razer HyperSpeed Wireless, Bluetooth, and USB-C wired connections. Switching between devices is fast and intuitive, allowing seamless transitions from PC gaming to a laptop or tablet setup.
Battery performance is equally impressive, with the keyboard capable of lasting hundreds of hours on a single charge under typical use. Even when running bright RGB effects, it holds up well against competitors, proving that slim design doesn’t have to mean compromised endurance.
Every element of the BlackWidow V4 Low-Profile feels deliberate, from the precision machining of the chassis to the finely tuned switch mechanisms. It’s a keyboard built to impress—not only visually but through its impeccable tactile feedback and ergonomic efficiency.

The doubleshot PBT keycaps play a crucial role in the keyboard’s overall performance. They offer a textured, matte surface that resists shine and wear while maintaining a premium feel under the fingers. The lettering is crisp and permanently moulded into the keycaps, ensuring long-term legibility even after extensive use.
Razer’s signature Chroma RGB lighting elevates the visual appeal, providing millions of colour combinations and dynamic effects. Thanks to the unique circular stem design, illumination is evenly distributed, creating a soft yet vivid glow across the entire board. Whether you prefer subtle ambient lighting or full-spectrum animations, the lighting is customisable through Razer Synapse.
Wireless versatility is another major feature, with support for Razer HyperSpeed Wireless and Bluetooth connectivity. Users can pair up to three Bluetooth devices and switch between them instantly using shortcut commands. The low-latency 2.4GHz HyperSpeed connection ensures near-instant input response, making it ideal for gaming where split-second timing matters.
Battery efficiency has also been a key design focus. Razer claims up to 980 hours of runtime in power-saving mode, depending on usage and lighting settings. Even outside of that mode, the keyboard delivers impressive longevity, reducing the need for frequent recharges and allowing uninterrupted productivity or gaming.
The onboard controls add a layer of convenience, with a multi-function roller and dedicated media keys for adjusting volume or skipping tracks. These are complemented by additional buttons that can be remapped via Razer Synapse, giving users more flexibility to tailor the keyboard’s layout to their preferences.
Speaking of software, Razer Synapse 4 serves as the control hub for personalisation. From lighting effects and macro creation to key remapping and performance tuning, every detail can be fine-tuned. The interface is comprehensive yet intuitive, appealing to both newcomers and experienced users.
One of the more interesting inclusions is the Razer Snap Tap feature. Designed for competitive gaming, it prioritises the most recent key press between two directional inputs, allowing faster and more precise movements in titles that rely on rapid direction changes. It’s a subtle yet effective tool for players seeking a technical edge.
The BlackWidow V4 Low-Profile includes hybrid onboard memory capable of storing up to five custom profiles. This means your macros, lighting preferences, and performance settings travel with you—ideal for players who compete or work across multiple systems.
