Excellent quality foam, fits the case perfectly. Worth the wait

Overall, slow to ship and one of the corners of the foam had a tear in it. Otherwise, pretty good product if you can wait

Took over 2 months for my foam to arrive, by the time it did I had already sold off the board I was going to use it for. Also came with a small rip in the foam. Honestly not worth the money and the wait time. Even though it mentioned there would be extended waiting times, it said only 2 weeks, not 2 months. You are better off cutting your own foam.

So I've decided to experiment with stock creams and wanted to know just how well the PCB and plate foam silences the keyboard in general. Obviously, unlubed creams are not quiet, so I purposely used these as an example.

Overall, the foam significantly reduced sound, especially in the low to mid frequencies. The echo / reverb is now very well suppressed. I was surprised to find though that the foam did not really affect the spring rattle and ping of the stock creams. The springs still had a similar tone and timbre after adding foam. I was expecting the pitch and reverberation to change, however, all that was affected was overall loudness and sustain (which is still great).

Fitting was extremely tight which was the only down side to the foam. I had to really tighten the case screws to make the case flush. I also ran into an issue using screw in stabs. I think the PCB foam was only meant for the stock kbd67ii clip-in stabs. However, I was able to cut small inserts in the foam to make the PCB foam fit. I only had to do it for two stabs. Being in this custom mechanical keyboard community, yo must know that jerry rigging happens often, so not really a problem.
