I'm interested to know if those rigdes are also on ZA series mice and other FKs.
I took apart my FK again to make the buttons a little better than I did before. I had only shaved down the area where the buttons bend.
I forgot to shave the button piece area that contacts the scroll wheel area.
When the buttons touch the mid shell it (obviously) creates more resistance. That resistance makes it more difficult to actuate the switches and it slows down your reaction times. When the screw (that holds the button piece onto the middle shell) is tightened it created torsion on the button piece, potentially bringing the buttons in contact with the scroll wheel area, which is why the FK can squeak. For now I decided not to use the screw. Also, instead of shaving the area highlighted in the picture, I shaved enough plastic from the button piece to create a larger gap.
With the combination of mods to the button piece, my FK's buttons feel almost like they have no extra resistance to actuate the (white) Huano switches. I click 10 times more within 10 seconds without feeling the same fatigue as before and it appears my reaction time have went down. The buttons are not as light as my G100s' Chinese Omrons, but at least the Huano switches give me better feedback. In the future I will put some Japanese Omrons.
I will do the same thing for my ZA13, maybe my AM too.
I don't see the point of removing the ridges that act as the pivot point for the button piece. Those ridges should keep the buttons from moving forward of the posts that hold them onto the front.Edited by popups - 4/6/16 at 7:13pm
