The Corsair Vanguard Air 99 Wireless enters the wireless keyboard market at a high price point, retailing for £239.99 / $259.99. Reviewers offer a polarizing verdict: the keyboard is praised for its design and typing experience, but criticized for its high cost, battery limitations, and complex feature set.
The board’s strongest elements are physical. It utilizes a 99% layout, an approach that successfully incorporates a full function row, number pad, and arrow keys into a footprint narrower than a standard full-size board. A column of dedicated macro keys sits along the left side. Its premium feel is achieved through an aluminum frame and soft bevel, while PBT keycaps provide comfort and a sharp aesthetic.
Standout visual features include a 1.9-inch LCD screen positioned in the top-right corner and a substantial, satisfying volume wheel, which receives consistent praise from users.
When it comes to typing, the experience is reported as exceptional for a low-profile device. Corsair employed pre-lubricated OPX optical switches. These switches feature a quick 1.5mm actuation point and produce a short, deep, and quiet sound, making them suitable for both professional office environments and gaming.
Functionally, the Vanguard Air 99 supports 2.4GHz Slipstream wireless, Bluetooth connectivity, and wired USB-C. It supports an 8,000Hz polling rate and features onboard memory to store five different profiles.
However, the pursuit of maximum features has created internal contradictions. The decision to use optical switches, possibly to save battery power, is offset by the inclusion of a bright LCD screen, per-key RGB lighting, and the 8KHz polling rate.
This feature load negatively impacts the user experience. Battery life plummets, dropping to roughly 10 hours during typical use when all features are active. Furthermore, charging is slow, requiring about three and a half hours. Users also note slow wake-from-sleep times, ranging from three to five seconds.
Other reported flaws include occasional wireless interference with other connected peripherals and rattly stabilisers that create a persistent ticking sound. For competitive gamers, the absence of true Rapid Trigger is viewed as a missed opportunity, especially since the software replacement is not a viable solution.
The software ecosystem is mixed. While it integrates with Corsair’s Web Hub—allowing configuration without installing the iCUE desktop application—it offers support for Elgato Stream Deck via six dedicated SD keys. The LCD screen can display various widgets, system stats, and media information. Nevertheless, critics describe the software itself as feeling incomplete, citing limited RGB flexibility and occasional unreliability.
Price also places the Vanguard Air 99 in direct competition with Corsair’s own Galleon 100 SD, which is only slightly more expensive but includes a full Stream Deck. Digital Foundry noted that a comparable board at half the cost would be their top overall recommendation. KitGuru summed up the board as a
