Apparently this is the first one of these in North America...don't worry it's nothing special. Don't bother.
It is however, capacitive sensing.

So...cheap...I should stick to vintage keyboards

Yep, it's a dome.

They're definitely not Fülhen me

A million cheap screws later...

Now this is interesting, domes over membrane...but isn't this supposed to be cap sense?

LOL, so they used a membrane instead of using springs (like Topre), foil (like Keytronic, Alphameric, etc.) or capacitive flippies (like IBM Model Fs).

Ugh, was this hand soldered...terribly?

At least the soldering job on the RGB leds looks good, because we all know these are the most important part

As for the scan rate, I did some basic scoping. At best the scan rate is 5.25 milliseconds (not including overhead from the controller). Not bad. A Model F is around 16 ms. Though not quite the 1 ms (1000 Hz) that marketing likes to throw around.
Conclusion:
Crap keyboard, feels like a normal rubber dome. Basically the only reason for the capsense here was to cheap out on diodes and get more durability over a metal contact dome switch.
Still, it's neat to see a some new attempts at doing cap sense. I've never seen the membrane over pcb method.

Hopefully I'll start posting lots of pics again in the near future, lots of inventory to go through...
