My 3-year-old barely puts this down, and I love that the screws and nuts actually fit the little tools instead of just rattling around loose. She's been "fixing" the coffee table for two days straight and hasn't lost a single piece yet.

The mix of wooden and plastic pieces is what sold me — the wooden screws feel sturdy, not flimsy like some other sets. My 3-year-old figured out the nuts and bolts on her own the first day, and it's kept her busy while I cook dinner.

My 4-year-old spends a solid hour screwing the little wooden nuts onto the bolts, and the mix of wooden and plastic pieces keeps it interesting. The tools are chunky enough for small hands to actually grip, which was my main worry.
