The cube foam is certainly not one of the most accurate, but can trigger clean with a cutter. You certainly can cut for sensitive equipment devices with a little "fine work" optimum negative molds. Overall, I have three of these cases in use for years and no one has been "disintegration". Another advantage is that it just does not look like a camera bag - it might as well tools or small parts are in the case - the case should thus nevertheless times be visible in the car, not everyone comes equal to the idea that maybe a few thousand Euro contents inside are ;-)
Overall, that gives 5 stars.
