Pros

  • The SMART Brick and charger avoid a separate starter purchase.
  • Light and sound responses make the finished build part of the activity.

Cons

  • The electronic layer needs charging and occasional app support.
  • The 473-piece build is better matched to LEGO’s stated 8+ audience than to a younger recipient.
