Really fun to build and play and test the build boxes we’ve only got 4 so far getting a no ther tomorrow and we love them the drawing machine is our favorite but has broke twice but there are extra parts on the website you would know if you’re subscribed to build box or hack pack

My daughter is seven boxes in and she has loved every single on so far! She tries to complete the build before the video ends. The most recent one's (boomerang car) battery ran out in one day because she sent me so many notes using the magnet and metal cup. So much fun! We will continue to subscribe!

I just finished level one of the building boxes and they all were absolutely amazing! Can’t wait to get level two! Would recommend for any parent who has kids who like science, physics, or engineering.
