After five years, I gave up my Matias quiet click due to its abysmal reliability. I had three units during that period: my original and two replacements under warranty. I love the keyboard and their customer service. But the interruption and administrative hassle were too much.
I use a Leopold with Topre 45g silent switches now. It’s not as nice IMO but it works all the time.
You share that experience with what seems a lot of people. The quiet clicks seem to have chattering issues.
I have probably been lucky. A friend had one switch that chattered, but I opened it up and cleaned out some of the lube and it was fine.
That is why I usually recommend the clicky switches. They seem to not have that problem. They feel even nicer to type on IMO, but I am not the kind of guy to spend $150 on a keyboard when I have one that I like (a 2015 secure pro that never had issues).
