Did you use a Dielectric grease on the Pcb, and how thick of an application of grease did you apply on the pcb to resolve the issue. I just order my FC660C from Korea, and if I too have this problem then I’d like to do it right.

I just used normal lube. A very very light application.
Really interesting. I was expecting a QC upgrade when they switched from China to Japan. Guess they screwed up some tolerancing in the process. Glad there’s a fix for it though.
Thanks for providing this, it was really informative. I’ve been having issues with my 55g domes where it sounds like it’s sticking to the PCB. I’m going to try to lube my RF PCB and see how that goes.
What about the case? Is it warped (not all feet touching the desk)?
I see a lot of people complaining about it.
Hey all, this is my first Keebtalk post but thought I would post this here.
I just received a new/silent FC660C and the Backspace and right Shift keys are crooked 
Other than that, this board is great. I have the beige/grey and grey/blue one as well.
what? you have 3 of them?? Did you pop the key off and try to reseat it?

Wow, Leopold & Topre both letting quality slip hardcore! 
Warped cases, warped keys, scratchiness in the sliders, clicking springs, & god knows what else will pop up. I’m glad I got my 660C when I did. Because while I’m sure they are awesome feeling boards even with the issues I would be a very upset customer if my board came any of those problems. I mean were talking about boards that cost over $200 off the shelf!
As far as the crooked caps go, Topre 9009 had a similar issue with some of the longer keys. I believe a lot of people fixed it by hitting the key with a hairdryer while it’s still on the board & turning in the opposite direction of the warp while the key is still warm.

Yeah, I’m a dedicated FC660C user for life 
I have tried reseating both keycaps and there’s no noticeable improvement.
Here is a pic of a grey Backspace keycap from my other board on the new board - it must be a bad/crooked keycap stem
Yeah, I’m lucky enough to have the original China version, newer Japanese version and now the newest version. For me, both Japanese versions have much better keycaps and they’re thicker too. The newest one also has a PBT spacebar.

Love my silenced FC660C. I can totally understand why you would want more of them! Too bad about the crooked cap stem. I wonder if the retailer would allow a return?
I bought it off widebasket, I’m patiently waiting for his reply 
Unfortunately crooked keycaps have always plagued topre keycap production regardless of production date/location. Some people get luckier than others when it comes to their topre keycaps.
There is also a certain amount of optical illusion that does sometimes appear as Ripster has documented: THE McRip EFFECT

I have one of the new low noise Fc660cs, my backspace looks exactly the same. My shift seems fine. Vendor was mechanicalkeyboards,
I have a low noise one I just got a few weeks ago and can’t find any of the flaws you’re mentioning. Might just be luck of the draw.
Have there been any problems with QC regarding FC660Ms?
have you contacted them?
I’m likely going to be buying an FC660C today.
Firstly, what are everyone’s opinions on the stock 45g vs the silenced?
Second, are any of these issues still present in current boards that anyone has noticed?
Go silent. It’s amazing.
