The RK89 is a compact keyboard that’s 14.1 inches wide, 5.1 inches deep, and one inch tall (with the dual-position flip-out rear feet retracted). KINGKONG89 uses an attractive ice blue lighting scheme that can be controlled with Fn + key combinations. The keys are plate-mounted three-pin brown switches similar to Cherry MX Browns, and the ABS doubleshot keycaps have layers of sound-dampening foam pre-installed that reduces rattling and vibration compared to fully hollow designs. The RK89 has two USB 2.0 passthrough ports on the top right, but they’re disabled in wireless mode.
kingkong 89 tested it with a 70-inch USB-C to USB-A cable for a wired connection, and performance was solid with no missed keypresses.
