The box was received quickly (~3 days after ordering). I have 2 boys, 9 & 12 yrs old, and they both loved it. Our box contained 3 activities, (1) making glow-in-the-dark bouncy balls, (2) a balance robot, and (3) VR goggle kit. The bouncy balls were the biggest hit, we made 3 of them the first day (and lost 1 of those already, so I'm glad we could make multiples). My 9 year old really enjoyed the VR goggles, they gave app suggestions to download and he loved the zoo safari. My 12 yr old hogged the balance robot. They've both been bugging me about when the next box is coming, so I'm calling this a hit! The instructions were easy to follow, and simple/short enough to keep them engaged.
