HONKID Keyboard Foam, Sound Dampening Foam for Mechanical Wired Keyboard Bottom, Made of LE-20 Poron, Black (H 3mm)

It's really hard to put into words how this works. If you are looking for a deeper thock sound and premium feel for your switches, this is the kit for you. I also paired this with a Poron gasket and pads (the little squares with cutouts that the switches rest on). With all three kits installed it takes your keyboard to enthusiast level. The foam needs to be cut to the desired size to put on the bottom of your board. That was easy enough just measure and match. Depending on your board you might have to make little custom changes, but it is worth it if your into modifying. For mine I had to make a little u shape cutout for where the USB-C port was as this raised it to much and wouldn't align with the port.

Product was the right size. It didn't stink. I got what I paid for. It did nothing to dampen or change the sound of my mechanical keyboard (keychron, plastic casing, brown switches, nothing special). It was worth a shot. Your mileage may vary. Really it just depends on the keyboard case you're working with.

Great. Thanks

It's nice you cut it however you wish. Works.

I got this for my first ever experience assembling a keyboard, so my opinions are naive. But, I think this works well! I was assembling a 75% Artemis Paragon keyboard, which doesn't sell components like foams, so I needed something I could customize. I did a shoddy job cutting the foam, but it was just the right thickness for everything to be nice and snug (and the sound is quieter too).
