The Corsair K100 AIR is a mechanical gaming keyboard with a low-profile design and a brushed aluminum frame. This keyboard uses tactile butterfly-style switches, which offer a typing experience similar to many laptop keyboards. It also supports a maximum polling rate of 2000Hz using a wireless connection or up to 8000Hz when connected with its cable. Extra features include per-key RGB backlighting, dedicated media controls, and versatile wireless connectivity with the ability to pair multiple devices simultaneously, including computers, consoles, and mobile devices.
Our Verdict
The Corsair K100 AIR is an outstanding gaming keyboard. It has impressive overall build quality and exceptionally low latency, supporting a maximum polling rate of 8000Hz using a wired connection or 2000Hz with a wireless connection. The low-profile, butterfly-style switches have a light tactile bump to overcome before actuating. However, they still feel very responsive due to an extremely low pre-travel and total travel distance. The low profile design of this keyboard also makes it comfortable to use without needing a wrist rest, although the keycaps themselves feel less high-quality than other aspects of the board.

The Corsair K100 AIR is an excellent keyboard for programming. It has impressive overall build quality, supports multi-device pairing with up to three devices simultaneously, and allows you to program macros to any key, either directly on the keyboard or using the customization software. Its low-profile design makes it comfortable without needing a wrist rest, and the low-profile butterfly-style switches provide a satisfying tactile typing experience. The keycaps are very stable and have shine-through legends, which is helpful if you like to work in a darker room. However, the keycaps also don't feel as high-quality as the rest of the keyboard.

Though not designed specifically for it, the Corsair K100 AIR is very good for use with a home theater PC setup. It connects wirelessly and can pair with up to three devices simultaneously. It also has dedicated media keys and shine-through keycaps so you can see the legends in a darkened room. However, it's fairly large and surprisingly heavy for its size, so it isn't the easiest keyboard to move around.

Popular Keyboard Comparisons
The Corsair K100 AIR is a high-end mechanical gaming keyboard with a much thinner design than the majority of gaming keyboards available. It's even thinner than similarly-priced flagship low-profile options from other major manufacturers, including the Logitech G915 and the Razer DeathStalker V2 Pro. Compared to these two keyboards, the Corsair K100 AIR supports a higher maximum polling rate of 8000Hz using a wired connection (or 2000Hz when connected wirelessly) to ensure the lowest possible latency while gaming. It also uses butterfly-style mechanical switches, which are very stable and feel high quality, but they're also more mechanically complex than the more conventional mechanical switches found on either the Logitech or Razer keyboard. These butterfly-style switches are only available as a tactile type switch, while both the Logitech and Razer models have linear, tactile, or clicky switch types available.
