Happy Hacker KB - Pro Hybrid
This design goes back a long way - I bought my first around 1998 or 99 I think. I had forgotten all about it, but then I made friends with a couple of Russians who were big into them. That was in Berlin sometime around late 2020, so that’s instance the first.
These are build by PFU Limited in Japan still (I think), and have Topre switches which are ostensibly legendary. They’re definitely unique amongst enthusiast kbd switch design.
Pro Hybrid
4 slots for BT pairings - this it the BT version of the original.
Pro Hybrid Type-S, Japanese Layout
Same BT setup, this one has “silent” topre switches which are also smoother and slightly higher resistance than the original.
