What age is best for a first Snap Circuits kit?

Verified-purchase reviewers generally point younger builders (around ages 5-7) toward the simpler Snap Circuits Beginner set, while the Jr. SC-100 and Classic SC-300 are positioned for roughly ages 8 and up. The Beginner kit uses fewer parts and larger, simpler projects; the Classic SC-300's 300+ projects suit kids who want to keep progressing.
