I just bought this keyboard as it is one of the few models that has cherry mx silent reds. I have a corsair k63 with cherry mx reds which I wanted to replace because even after adding o-rings to the corsair it has an annoying high pitched sound when typing too quickly, regardless if bottoming out or not. I realized it was due to the low quality keys on the corsair and was looking for something a little higher quality. I opted to try a leopold due to its reputation. For the same price as this keyboard you can get a similar one with more "features", e.g. USB pass-through, backlit, etc. but I was willing to pay more for less features but higher quality.

I am very satisfied with this keyboard. Leopold stands up to its reputation and I love this keyboard. It's very pleasant to type on and has a high quality feel to it. While it's not absolutely silent, the higher build quality and the silent reds makes the sound a lot more lower pitched and very tolerable for those sitting around you. Typing produces more of a low "thudding" sound, rather than a high "ticking" sound. This sound reduction while still maintaining the comfort of a mechanical keyboard is exactly what I was looking for. I'm very happy with this and definitely consider it an upgrade over my k63. I recommend for those looking for a quality, quieter keyboard and you're willing to give up on the frills to get it.
