Our Take

Best for: Competitive FPS gamers wanting a responsive, compact keyboard.

The RK C84 HE brings premium hall effect technology to a budget-friendly price. 5mm, letting you set each key for lightning-fast FPS triggers or deeper typing presses. The 8K Hz polling rate (8x faster than standard keyboards) ensures near-instantaneous input registration, while Rapid Trigger enables quicker peeking and stop-shooting in Valorant and CSGO. The 75% layout saves desk space without sacrificing arrow keys, and the PBT keycaps resist shine over time. Triple-layer foam padding makes the typing feel solid and satisfying. The main tradeoffs are the lack of a full numpad and wireless connectivity, but for a dedicated wired gaming rig, this is a non-issue. 99, this is one of the most affordable hall effect keyboards on the market, offering features typically found on $100+ competitors.

Price Analysis

At $54.99, this is 27% off the original $74.99. For a hall effect keyboard with an 8K Hz polling rate and rapid trigger, this is an exceptional value. The flash deal pricing makes it a great time to buy.
