I've generally ordered foam direct from the manufacturer in the past, which was always an exact fit. This foam needed to be cut, since there were no wheel cut-outs in the first two bottom layers like are in the factory foam inserts. Just a bit of extra work that is not needed in OEM foam. Other than that, it is a good quality foam.
I needed to replace the pic-n-pull crap that came with the case. This was perfectly sized and easy to cut. Little tip, I used a filet knife to score the outline and a cheap “ginsu” style that I modified with a sharp tip to cut out.
