"My 4 year old and I had fun building two versions of this Creator box. He loves playing with his bike, it was a 15-20 minute build time since my son built it by himself with little assistance from me. My son wanted this for Christmas and Lego.com customer care was exceptional in helping me locate this set in their inventory when it was sold out online. The look on my son's face when he opened his present was priceless. Thanks Lego."
