Amelia K. ★★★★★

The 7 model builds kept my third graders busy for a full afternoon, and the gears clicked together snugly enough that nothing fell apart mid-rotation. Watching them test the crank mechanism on the different models really made the science concepts stick.

Ryan H. ★★★★★

My son built a working car and a hand mixer in one afternoon, and the included gear pieces are sturdy enough for his enthusiastic play. The instructions were clear enough for a 7-year-old to follow with just a little help. Just the right challenge for a curious kid.

Benjamin ★★★★☆

Kids really got into building the hand crank models; the instructions were clear enough for my 8-year-old to follow with just a little help. Only wish it came with a few more gear pieces for even bigger builds.
