I loved the sound but dental bands changed the feel too much for me.
I contacted a company in China that can make 0.5mm foam disks.
Moq was 500 at $50... cheaper if you buy more of course.
I was going to grab these and try them out but when I returned my HHKB to stock I realized that I actually don't mind the way it sounds at all.
Although I love the soft rain like thuds when it was modded, I think the stock HHKB sounds pretty good too.
Hmmm wonder if I should bother doing it to my Novatouch...
