Like Legos, the playset is open-ended. While the Deluxe Base Station has enough parts to build a pair of towers connected by a bridge, a couple of rovers, and some other parts like a rotating sign, you can add it to other Circuit Explorer kits to go beyond the picture on the box. And for six-year-olds and up, the direction printed on the toy is usually easy enough that you can skip the directions, meaning parents can join in the fun, or rest assured kids can occupy themselves. Even a simple kit has enough parts to build a cool LED flashlight. Really our only gripe is this kit needs 15 AAA batteries. But hey, if your kid is STEM enough to play with this, maybe they can handle battery management too? Every product on Fatherly is independently selected by our editors, writers, and experts.
