YIMAGUJRX Sound Dampening Foam for Mechanical Keyboard Bottom, Made of YM40-Sponge (10mm Thick)

Great kit. Comes with everything u need to mod your keyboard

Picked this pack on a whim to install along with a one piece 75% Poron switch plate foam.The 3mm Poron foam sheet replaced the random lightweight closed cell foam I used for the bottom case foam. It made the most difference in dampening the sound of the keyboard out of this pack. It's also squishy enough that I didn't have to cut openings for the Kailh hotswap sockets unlike the old foam. The plastic backing made trimming to size with a with a knife very easy. And the crease from the foam being folded in half as seen in the picture went away pretty quickly after taking it out of the bag and unfolding it.The Poron switch pads was something I was curious but ended up on the fence about it. I stuck a few on to try and maybe because I'm using Gazzew's Boba U4 as my main switches there wasn't any difference from what I could tell. I did try some other switches I have and again it I didn't really notice anything.The individual EVA switch plate foam I didn't use as I'm using a one piece Poron version.So I pretty much used the just Poron foam sheet from this pack. It was a few bucks more than the 3mm Poron foam only listing sold by the same seller so it still made sense to get this and have the extra stuff for a future project.

The media could not be loaded. Its really thick. I used this on my modded anne pro 2 with matcha green switches. I took a star off because the package was ripped open

Opened up my royal krudge keyboard stuffed some foam in carefully while avoiding overstuffing to avoid keys pcb board from bending and put it all together, keyboard sounds amazing now happy works great fits well when you cut it with a exactocutter worth money spent

Put this in my TOFO 60 which had a lot of ping before with previous material. Most of the noise is gone except for some slight switch noise but probably just because tactiles.Also had a budget WK61 laying around for testing purposes, that also had a ton of noise going on, threw some of this in there, can't complain about the result, still a little noisy but overall I'm happy with how it turned out.Will probably continue to use this stuff as long as I am building keyboards, love the sound profile it gives.

i thought this would be thicker. I didnt install l it under the keyboard I wanted to layit down and put keyboard on it. I kept it but plan to find thicker foam to use.This was not what I expected.

Wanted to mod a cheap gmmk 100% and make it as silent as I could since I was going to use it in an office space. Was able to pack the small switch pads, films and the large pad inside the gmmk case, it was a really tight fit and most likely overkill for the keyboard, but i think It came out great.This bundle of pads and films are great to easily mod a keyboard

I've never worked with poron before, just neoprene and some other foamlike dampening materials like Zip-N-Fit liner, but it seems like it will do the job. Along with the foam, I received a large pry tool which could come in handy when you're tinkering inside a keyboard I suppose.The piece I received was soft and flexible with a smooth, shiny plastic side adhered to the back to make it easier to cut and prevent warping. I don't think you can peel it off, but it shouldn't be a problem inside your device. It's also perforated with a few predefined sizes to get you started. Unlike some other pre-cut dampening foams I've seen, the poron itself is not perforated--only the backing. Personally, I prefer how it's handled here.My piece measured 4-7/8" by 16-7/8" (almost 5"x17"), and it was just under 3mm thick. I'm not sure if the crease in the middle would eventually flatten out, but the material is so floppy that it's not a big deal. It's most likely going to be buried deep inside your keyboard anyway.Overall, I'm pretty happy with this. It didn't help as much as I was expecting to reduce the hollow sound in a non-keyboard device (Snack Box Micro), but I'm sure it will be fine for its intended use. I am, however, docking a star for the price. $12.99 seems a bit steep considering that I've seen boutique keyboard shops sell foams a few bucks less. Of course, you have to factor shipping costs and taxes, so this still might come out cheaper in the end.
