Ok I have received my Filco Majestouch 2 Tenkeyless HAKAU (White) with Silent Reds.
TL;DR: IT'S AMAZING. No ping, though I can hear the springs a little bit under the "e" key. Regards the left shift: only if I press on the right side of the LEFT shift key and on the LEFT side of the RIGHT shift key can I hear a bit of a squeeze. These are definitely the stabs. So lube I guess?
As for quietness.. it really IS the quietest board I have around (compared to topre 55g plate mounted, hhkb 45g, clears, and browns). It is very very smooth, almost as smooth as topre. It feels better for me personally actually. It feels like those acrylic case macintosh keyboards with white keys. Very very smooth. Bottoming out also feels dampened, like typing on vilt or something.
I immediately installed red 40A o-rings. AND I immediately removed them. They removed travel too much and the typing experience WITHOUT o-rings is soo much better. I never thought I would say this: red o-rings suck for mx reds. Perhaps try out black o-rings? Who knows.
ASK ME ANYTHING
