Works perfectly, shipped quickly
Foam needed to be cut in order to fit in Drop Alt, despite that it makes a world difference in alleviating case ping and the hollowness of the board
I owned original ALT and it fits perfectly. If you care so much about acoustic of your keebs and make it more solid from the inside just order it.
The lower two pieces of foam worked as expected, The top foam needed to be sliced in two pieces and the corners trimmed to fit. Nothing that a sharp pair of scissors can't fix.
I used it for my Alt Low profile. Had to modify some parts of the plate foam, but everything fit pretty easily. It makes the board sound great.
Had to make a few minor cuts for the case and plate foam due to design changes by Drop (I think, at least) in order for it to fit. I just used scissors. You’ll notice where you need to cut when you see it. Definitely changed the acoustics for the better! The whole board sounds and feels better.
