Here's the beast. My initial assessment was it's a keeper, all red and compact with pointer and keyboard in one. But my Cherry brown-trained fingers soon grew tired on this one. I received Kishy's black board around this time, and quickly learned popo keyboards are firmer than normal Cherry Blacks.
The popo blood-proofing membrane acts like an extra spring. The key shafts are tightly sealed in the membrane, so when the keys are pressed, the membrane deforms, and it really-really wants to restore itself aggressively. It's so aggressive that it's possible to get the keycap held in the fully-down position, held by only the friction and resistance to deformation of the membrane.
While sealed solidly against the keys, membrane blood-proofing is easily dislodged along the case boundary edges by curious forceps, so then I had to take the beast alla way apart. I'd broken the water-tightness before ever testing it, D'oh! Just as well. There was a fine black powder on the membrane where the keycaps didn't cover it. It rinsed right off, but all the joking about body fluids forced a thorough cleansing.
Oh, the black spots on the previous pic are places where water drops remained when I re-installed the membrane, not black blood.
I'm contemplating a replacement of blues for the blacks, but the blues I already have are mostly heading into a Kinesis Contour, so I can have both a blue and brown Contour experience, as the mood takes me.
I'm sort of stumped with what to do on this project now.
