vex foam usefulness?

I’ve not had the chance to actually test out what they sell as “vex foam” here. Anybody out there: is it any good? Is it any different than the fun foam you can buy at a craftstore?

i made some nice bumpers out of it.
having foam as the main points of contact between your bot and the metal field surroundings can reduce static electricity messing with your battery/microcontroller.
i would quote the person i read this off of but i cant remember who it was
sorry dude i didnt properly quote:o
