Compared To Other Keyboards
The Razer BlackWidow V4 continues Razer's popular BlackWidow lineup of flagship gaming keyboards. The standout features this model introduces to the lineup are a handful of dedicated macro keys on the left side of the board and a maximum polling rate/update rate of 8000Hz, which means it can send information to your computer eight times more frequently. This higher update rate is a major factor in ensuring slightly lower and more consistent latency performance compared to some other gaming keyboards with a standard polling rate/update rate of 1000Hz.
There's a separate 'Pro' version of this keyboard called the Razer BlackWidow V4 Pro that has several additional features, including one more layer of sound-dampening foam inside the case, additional RGB lighting zones in the wrist rest, additional macro buttons on the left edge of the keyboard, and a programmable knob that Razer calls a 'command dial.' For more details, see the Differences Between Variants section above.

Test Results
The Razer BlackWidow V4 is quite large, and the additional column of dedicated macro keys on the left makes it slightly wider than most full-size keyboards. That said, you can reduce the footprint of this keyboard on your desk by removing the wrist rest if you prefer.
This keyboard is marginally lower (~2mm) in height than the similar Razer BlackWidow V4 Pro. For more details, see the Ergonomics section below.
The build quality of this keyboard is great. The lower chassis is plastic, the top plate is aluminum, and the entire keyboard feels very sturdy and has little or no flex. The keycaps are ABS plastic, but they feel comparatively high-quality compared to most ABS keycaps and have pleasant textured tops. There's a layer of sound-dampening foam inside the case, and the stabilizers are pre-lubed from the factory, contributing to a somewhat more premium feel overall. There are four rubber pads on the underside, and each incline foot has a rubber strip, which does a great job of keeping the keyboard in place. Additionally, there are seven rubber pads underneath the wristrest, which attaches magnetically to the keyboard.
The Razer BlackWidow V4 has two plastic feet on the back edge of the keyboard, providing two optional incline angles. There's also an included plush wrist rest that attaches magnetically and provides additional support while typing.
This keyboard's home row height is marginally lower (~2mm) than that of the similar Razer BlackWidow V4 Pro. However, this difference is so minor that both keyboards provide the same ergonomic experience.
This keyboard provides mediocre hardware customizability. It has plate-mounted cherry-style stabilizers, which are reasonably easy to replace. However, it doesn't have a hot-swappable PCB, so you'll need to unsolder and resolder new switches if you'd prefer a non-stock switch option. The switches have Cherry MX Style stems, but they have North-facing LEDs, which can cause compatibility issues with some keycap sets.
This keyboard has full RGB backlighting with individually backlit keys and additional RGB lighting zones on either side of the keyboard case. You can adjust the brightness levels and customize the lighting and effects using the customization software.
While the closely related Razer BlackWidow V4 Pro version of this keyboard has additional RGB lighting in the wrist rest, this keyboard doesn't.
This keyboard provides outstanding backlight clarity, and the legends are easily read in darker rooms. A faint red hue is visible when set to white-only backlighting.
This keyboard comes with a braided power cable. It retains some kinks from its packaging.
The Razer BlackWidow V4 is a wired-only keyboard.
This keyboard has six dedicated macro keys located on the left side of the keyboard. You can record macros using the configuration software or with hotkey combinations listed in the user manual.

Overall, the typing quality on the Razer BlackWidow V4 is good. The keys only exhibit minimal wobbling, and there's good spacing between keys. The keycaps are made of ABS plastic. They feel superior to most other ABS keycaps and have a slightly textured surface for added grip. Razer has also added a layer of sound-dampening foam and pre-lubed the stabilizers on modifier keys. Compared to older models in Razer's BlackWidow lineup, it delivers a smoother typing feel. Still, some of the larger keys have a noticeable wobble, including the spacebar and shift key. The spacebar, in particular, makes a noticeable rattling sound.
We bought this keyboard with linear Razer Yellow switches, which are fairly smooth. Still, they have very short pre-travel, which makes them well-suited for fast-paced gaming, but they may also feel somewhat too sensitive for typing if you aren't used to them. Unlike the stabilizers, these switches feel somewhat scratchy because they're not lubed from the factory. This keyboard is also available with Razer Green switches.
We tested the very closely related Razer BlackWidow V4 Pro keyboard separately with clicky Razer Green switches and found the feel of those switches was very inconsistent. Thankfully, the typing experience with the linear Razer Yellow switches doesn't suffer from the same inconsistency.
The Razer BlackWidow V4 has excellent typing noise performance. It has a layer of sound-dampening foam inside the case, and the stabilizers are pre-lubed from the factory, which reduces the overall noise somewhat compared to earlier models in this lineup. That said, the spacebar makes a noticeable rattling sound that's fairly typical of gaming keyboards at this price point.
We bought and tested this keyboard with linear Razer Yellow switches, which are very quiet and unlikely to bother those around you.
You can also purchase this keyboard with clicky Razer Green switches, which are significantly louder and provide an audible high-pitched click as feedback when you've actuated a key. These switches may bother those around you, especially in noise-sensitive shared spaces.
We bought and tested the Razer BlackWidow V4 with linear Razer Yellow mechanical switches.
This keyboard is also available for purchase with clicky Razer Green mechanical switches. See the Keystrokes section for more details about how these switches feel and perform.
We bought and tested this keyboard with linear Razer Yellow switches, which are lightweight and have short-pre travel, making them feel very responsive.
This keyboard is also available with clicky Razer Green Switches, which are a bit heavier and have slightly longer pre-travel. They also have a noticeable tactile bump to overcome before actuation, providing audible clicking noise, while the linear switches don't.
While we haven't tested the Razer Green switches on this keyboard, we tested them on the closely related Razer BlackWidow V4 Pro. On that keyboard and several other Razer keyboards we've tested, we've found that the Razer Green switches are noticeably inconsistent in how much force it takes to operate them. Additionally, some individual switches may not produce audible clicking feedback. It's worth noting that we haven't experienced this same inconsistency with Razer Yellow switches either on the Razer BlackWidow V4 or other Razer models. If you have this keyboard with Razer Green switches, we'd love to hear about your experience in the discussions at the end of this review.
The Razer BlackWidow V4 has exceptionally low and extremely stable latency performance. It offers an extremely responsive-feeling experience for gaming in any genre at a casual or competitive level. We tested this keyboard with the polling rate set to its maximum setting of 8000Hz.
The Synapse 3 software is well laid out, easy to use, and offers plenty of adjustable features. You can customize the RGB lighting, set macros to any key, and reassign keys. You can also enable a 'Game Mode' to disable Alt+Tab or Alt+F4 commands and assign a Hypershift button to enable a secondary layer of programmable keys. Note that certain settings, including custom RGB settings, can't be saved to onboard memory and require the software to run in the background.
Like the software options from other major manufacturers, this software receives criticism for requiring frequent updates and taking up disproportionate system resources. This software may be frustrating if you prefer more lightweight software options or no software at all.
This keyboard is fully compatible with Windows, macOS, and Linux. However, the customization software is only available for Windows, and certain OS-specific buttons don't do anything by default in macOS, including Scroll Lock and Pause/Break.
