This was a fabulous box for an older (I'd recommend 10+) STEM oriented child! My 11 year old son is very smart, loves Math, and has mild ASD (so in his case, patterns, codes, logic endlessly intrigues him). He had aged out of many of the other subscription crate options, and those that required complex fine motor/building skills (Tinker Crate, etc) were not his top strength. But the concepts here were new to him, and even enticed him to paint/draw/craft. This crate helped him decide STEAM (with the Art added) might be as great as STEM :) 5 stars!
