Mistake: Buying for Pure Fidgeting or Instant Gratification.
Correction: These are not stress balls or spinning tops. They are contemplative objects that require patience and focused attention. The reward isn't a quick dopamine hit, but the slow, dawning understanding of a mechanism. If you need constant motion, pair a puzzle with a separate fidget item. Expect to sit with it, turn it over, and listen. As one reviewer put it, 'Finally, a puzzle that feels like an artifact, not plastic.' The satisfaction is in the ritual.
