KBDFans Mechanical Keyboard Spacebar Foam

I was looking for spacebar foam for some CSA keycaps (profile is between cherry and OEM). I wasn't sure if the 6.25u 3.5mm or the 6mm would be the better fit, so I ordered both. The 6.5mm was a bit too tall and a bit too wide for the profile, but the 3.5mm fit nicely (could have probably been 4 or 4.5mm with this profile). The adhesive was nice and the sound improvement is worthwhile. The 6mm had a middle piece of foam for the switch itself that the 3.5mm did not (perhaps typically 3.5mm clearance doesn't allow for said piece); I used the middle piece from the 6mm set and it worked quite nicely. Good quality, good fit, good price... Worth the upgrade. I'm buying some for my enter and backspace keys as well and cutting it to size.

Gave it three stars because I couldn't use it. Sticks very well but it's to thick for my spacebar
