Great kit

Fits perfectly, with cutouts for all the little details. Be careful when handling the foam, since some parts are so thin that they can easily break. I paired this foam kit with some masking tape on the PCB as well and now the K4 sounds amazing.

Unclear shipping information

Shipping information was unclear and misleading and responses from you customer support were quite short and seemed to care very little about my order. I think I’ve managed to re-arrange delivery but still not sure.

Not bad, but not perfect

Overall this kit worked well enough to improve the pretty rough acoustics of the default Keychron K4, but the foam I was most excited for in the kit didn’t fit. Specifically the plate foam, which was so thick that it prevented the switches from successfully reaching the pinholes on the PCB. This resulted in a bunch of errant keystrokes or missed keystrokes.

And no matter what I tried (clipping the excess foam around the stabilizer wires, etc.) the foam was ultimately just too thick to sit comfortably between the plate and PCB without interrupting function. If it was even just a millimeter thinner it would likely have made the difference, but sadly it’s not.

Fits perfectly in my Keychron K4 V2. Sound difference is amazing.
