I wanted to reply to this thread with my opinion of FUKKA switches. I just took the time to lubricate and clean all of the FUKKA switches on an Omnikey 101p that I purchased from Ebay. I used teflon grease on the click leaves and left the sliders in a solution of 303 aerospace protectant overnight.
I've noticed that while the FUKKAs with grease are quite smooth and satisfying to type on, they do not compare to new complicated ALPS blues. I purchased a board of like-new ALPS blues from Didjamatic and I was astonished by the smoothness of the switches. It was like typing heaven.
While typing documents is definitely much easier with blue ALPS, FUKKAs are surely better for games like SC2 that require deliberate key presses. I ended up making more errors on a blue ALPS board while playing SC2 than I did on my Model M for example. My Model M is not as easy to type word documents on though.
FUKKAs are actually a good compromise between the Model M and ALPS blues when it comes to resistance.
The one thing that I absolutely hate about FUKKAs is the quality of their switch plates... The two piece design is very easy to bend if you are not incredibly careful when assembling and disassembling switches. Furthermore, if you bend the switch plates, it can be nearly impossible to get them bent back to a good position. I had to replace 5 FUKKAs on this board with original complicated ALPS because their switch plates became impossibly bent out of shape.

I also don't know if this is the fault of the specific switches on this 101p, but not of these FUKKAs click as loudly as the complicated ALPS that I have. Some of them hardly click at all. This doesn't appear to affect the quality of actuation, however it is noticeable.
