I was concerned about the tolerances of the foam, worried that they might rattle around in the case, but they're actually just a hair thicker than the spaces so once everything is pressed in and screwed down, the foam is compressed just a tiny bit which provides a very snug fit.
As for the feel/sound, it makes for a much more solid feel, and an almost richer sound. No more hollowness or case ping.
10/10 worth it, even though it took a while to get to me.
Bought this for my NK65 v1 to get rid of the terrible case ping. Had to modify it a bit to fit properly but I knew that before buying. Unfortunately, it didn't fully get rid of the ping. I'm not going to knock it down as it's not really meant for this board.
The foam did take a while to arrive but I also knew that. I really appreciate the packing as it keeps the foam straight, unless your mailman decides to completely fold it.
Amazing product my keyboard doesnt have hollow sound anymore. Interesting package every packing paper is a cia case. One con is puttin in switch, you have to fiddle around or it wont go in because of the foam. 10/10 would recommend
My keyboard went from disappointingly pingy to amazing. Honestly, the waiting really wasn't that bad...you get used to it with this hobby.
foam fits, great and fills in the empty space in the Tofu very well
I have the best sounding keyboard now, fits perfectly
