I've used the foam to build my own camera Inlay for my Backpack. Because I needed to pack so much into such little space, I was worried it might not be sturdy enough, but after using it a few times now, I'm really happy with the way it holds and doesn't rip. I had a few problems cutting, mainly because my items are so deep, that I had a hard time getting the cuts vertical, but it ended up good enough. Also because of the depth of the items, making paper templates first worked best for me. I went for two 50mm Pieces on top of each other, to get 100mm. The Camera and Lens Cutout at the top are left exposed for quick access. Overall, I'm really happy with the Sturdiness of the foam, and especially that it doesn't rip. As for the cutting. the first Scalpel I ordered didn't work great, but after finding one like they include in their cutting kit, it worked quite well. The peeling wasn't as smooth as I envisioned and left quite the uneven Bottom, but with the scalpel I could remove the most uneven parts. If its because of the Structural Integrity of the Foam I'll definitly take that over a better peel, but otherwise, that would be the only complaint I have.
