In fairness the filco was a well used example. But the is no way I'd call a ducky low quality, no idea where that came from.
Really like the MX blues. Never had a problem in games as I always press the keys all the way down. I do see how it could be a pain if you didn't though.
I tend to press the button till it actuates and hold it there, I try not to bottom out, it causes pain after a while and obviously bottoming out causes a fair bit of noise.
I haven't no, they were all rocking blues. Not very easy to find things mech keyboards, the blackwidow belongs to a mate and the filco was owned by a guy in the office at work. They're the only other two I've ever seen in real life
