When IGN reviewed the Logitech G613 wireless keyboard, it was dubbed the “world’s first mechanical wireless keyboard,” and it’s pretty great. There was just one little problem; it wasn’t backlit. Logitech argues that for a wireless device, a backlight is simply too taxing on the battery. Corsair obviously isn’t buying that logic though, as it’s new K63 keyboard (See it on Amazon) / (See it on Amazon UK) is both mechanical, wireless, and backlit, making it truly one-of-a-kind – at least for now.
