https://www.keychatter.com/2018/08/16/unpacking-the-kailh-box-switch-debacle/Read it. Was enraged. Perfect storm to make keycaps crack, my ass. Present the data from measurements and manufacturer, sure. But how could you overlook the community so resoundingly?
It seems Seth either doesn't read forums or just thinks we are all lying. He thinks the problem is not widespread. He summises it's a combination of keycaps and switches both being out of spec and only in the "perfect storm" you will have broken caps.
The thing is, anyone with GMK caps sitting on box switches has broken stems. But they won't know it until they go to switch out those caps to another board. We're going to see thousands of complaints over the years to come.
This was the kicker for me:
"You should be able to use any old Box switches you have on hand, although if you have expensive or older keycap sets, you may want to proceed with caution before pressing them onto Box switches"
Would ANYONE in this forum give the same advice? Hell no. You should NOT put expensive keycaps on box switches. End of story. Sorry to be an alarmist, but I have 3 ruined sets of GMK caps. They break (usually on first placement) on EVERY box switch I have tried. I have tried EVERY box switch. 2 different vendors, 4 different purchasing times. The GMK sets are 4 years apart in manufacturing. Also, my SA lime set was all cracked as well. But I've seen other people report that issue and I don't know if it was on Box switches, so I'm discounting it.
PS, still have 900 switches to sell.
