Didn’t Help Much with GMK/ePBT

The foam is cut precisely and fits well but, at the 3.5mm size, it doesn’t help much with sound. I’d honestly just buy something denser like sorbothane and cut it yourself. You’ll likely get better results from that.

Very Nice but It has a Major flaw

I bought these a few days ago, while testing out some durock plate mounted stabs. When I got to testing out the spacebar I decided to install this foam on the spacebar. Just to figure out it doesn't work with traditional plate mounted stabs. I would recommend going with these anytime if you are going to use screw in stabs but if you are going to use plate mount you shouldn't buy this. In summary these are amazing 10/10 would recommend unless your using plate mounted stabs and then in that case you might has to do some modifactions to the foam.

Absolutely Phenomenal (NOT FOR PLATE MOUNT STABS)

Do you have screw in PCB stabs? Buy this for your larger/thin spacebar. I bought the MT3 (6mm) and it fit snug as a bug. This also fits Tai Hao cubic profile spacebars which is what it will be used for. Tai Hao cubic spacebars are much thinner, and so the sound produced is a bit high pitched for my liking. These foam inserts changed the game for it, producing a fuller deeper sound. To be honest, I'm not even removing the adhesive strip as it doesn't move after placed. NOTE: They're so precisely cut that with plate mount stabs there is an extra housing around where the stab mount goes into the housing, and so it will not let the spacebar depress. It hits the foam where with a PCB mount stab there is nothing for the foam to come in contact with.

Spacebar foam

The spacebar foam was blocking the way of the spacebar pressing, so i couldnt press the space bar because the foam was blocking the stem part.

Great product

Perfectly fits GMK space bar, not to thin, not to thick so the space bar doesn't feel mushy.
