It's a teeny bit pricy for what it is ? expanded foam ? hence only four stars in total; but if what you need is a thoroughly professional, fitted, custom inlay for your 2U drawer unit, then this is the only gig in town. The foam is pre-perforated into little cubes which you can easily dig out with your fingers to create custom recesses for whatever mics (or other pieces of delicate kit) you want to reside in the drawer ? though once the cubes are plucked out, you can't really add them back in again, so it's worth planning the layout in advance. Once you're done, though, everything has its own padded home and nothing's rattling about getting damaged.
