Looking like clusters of six rhombic dodecahedrons, these puzzles are members of the Diagonal Burr family. Assembly is moderately difficult due to the dexterity required to align the two halves of the puzzle just right in order to get all of the pointy tips properly overlapping each other. Disassembly (i.e. "busting" the cluster) can be quite tricky because of the awkward placement of six fingers required to begin pushing the two halves apart.

The classic version of the Cluster Buster has all six pieces identical in shape, whereas the improved version uses three different piece shapes which come in pairs. The slight variation between piece types in the improved version makes both assembly and disassembly more difficult. The truncated version is essentially the same as the classic version, but with additional cuts which accentuate the three 4-fold axes of the puzzle.
