Corsair killing it these days with these keyboards.

@Hilbert Hagedoorn Have you tried orings? These reduce the key travel a bit but for gaming that does make the key response a bit faster especially double tapping etc. Usually with gaming you are going to be bottoming out and this cuts the noise down from that. I prefer the red orings as they don't impact the feel as much. Cherry MX Rubber O-Ring Switch Dampeners (125pcs) - WASD Keyboards Also I have a bit of advice for keyboard testing. Could you grab arguably one of the best production keyboards, the Leopold FC750R in Cherry MX browns or reds, add the red orings and use this as your baseline? This will give a tester a solid feeling, low noise, fast responding mechanical keyboard that would be a decent gold standard for typing/gaming.

Article regarding choice of o-rings that is worth a read, it;s pretty much up to individual preference wich to pick, most can be found for cheap in hardware stores, no need to pay more for special brand names when it comes to o-rings, as long as thickness and hardness matches ones preference. I wonder if the branded types can be ordered on request with 1-2 of each type in a test set.... like it is possible with guitar picks and other stuff.

I'm pretty sure Ducky is the OEM making this keyboard for Corsair. Check out the number keys they have that same funky inline number/special character design.
