The Corsair K70 RGB TKL is an excellent gaming keyboard that is a scaled-down version of the Corsair K70 RGB MK.2. This is a well-built keyboard with sturdy two-tone PBT keycaps. It has tons of gaming features like macro-programmable keys, full RGB backlighting, and a "tournament mode" switch that disables all macros and displays a single color so you can focus on the game. The unit features Cherry MX Speed switches that are very light to press for a responsive gaming experience, and linear Cherry MX Reds are also available. Still pretty good if you want to use it for the office and don't mind sensitive switches, shame every wrist rest design.
The Corsair K70 RGB TKL is an excellent gaming keyboard. Equipped with Cherry MX Speed axles are very light with minimal pre-travel distance. It also has very low latency for a responsive gaming experience. All keys are macro-programmable, have full RGB lighting, and are well made. It doesn't come with a wrist rest for those long gaming sessions.
The Corsair K70 RGB TKL is wired and cannot be used with mobile devices.
The Corsair K70 RGB TKL is perfect for office use. The build is really nice, and the two-tone PBT keycaps feel great in the hand. It has excellent typing quality, but the linear Cherry MX Speed switches don't have any tactile feedback, which can lead to more typing errors than usual. Ergonomics are not enough, and the lack of a wrist rest may put some people off.
The Corsair K70 RGB TKL is great for programming. You can set macros for any key, and it has full RGB backlighting. Typing quality is good, but the linear shaft body can be too light for mishandling, which can lead to increased typos. It's well made, the frame is solid and the overall workmanship and texture are good.
The Corsair K70 RGB TKL isn't good enough for home theater PC use, and since it's purely wired, it has to be connected directly to the TV and within range of its cable. It also doesn't have a trackpad, so you'll need a mouse to navigate the user interface. However, it has full RGB backlighting so you can see the keys in the dark, and it has dedicated media keys.
