An underrated mod
These are easily applied, and I experienced no difficulty putting the switches in after applying these. They definitely refine and clean up the sound of the keyboard, I interpret it as creating a bit of a quieter, poppyer sound.
Made my keyboard sound much better. I'm searching for that perfect sound, and these switch pads put me on the right path.
Nice for deep, thocky sound
Really easy to install, cut out precisely, make for a noticeably deeper thocky sound (on my kbd67 lite r3 w/ Gat Milky Yellow KS-3 Pros), maybe a little too deep and thocky. I believe PE foam would yield more of a marbly sound, so i may go that route later, but these are great for quiet, deep, thocky builds. Can be peeled up if lightly applied crooked. Press down after ensuring the pad is centered to stick it down. Apply with tweezers.
These pads are the most amazing lowkey mod you can do to your board. I've improved the sound and even feel of $500+ boards with these things and I will never build another without them. I personally prefer these to PE foam as they give a more "solid" sound while the PE foam sounds more "thin" to me, if that makes sense.
Might be Useless
They are not that difficult to put on [I used tweezers] to the PCB. While it was a bit time-consuming to do so, I am unsure of how much of a difference they make. The only time I have tested them was for the keys that need stabilizers [Backspace, Spacebar, Left Shift, and Enter] and the audible difference is very miniscule, if present at all. Therefore, I cannot fully recommend them as they do not hinder the keyboard sound in my opinion, but they do not add a whole lot to the sound signature.
