Reviewed in the United States on May 30, 2020
This book is Good Quality, Good Value, and Engaging for Mechanically Minded Children 8-16..We have bought a number of these books. Children ages 8-11 may need substantial adult help in building activities..Ages 12-16 would be more independent with these activities. t.
