CrunchLabs Build Box vs Green Kid Crafts

CrunchLabs leads on wow factor

vs

CrunchLabs Build Box and Green Kid Crafts both land in the same basket for parents shopping subscription kits, but they are built for different children. CrunchLabs Build Box is mark Rober's monthly mechanical toy, with the video to match, aimed at ages 8-14. Green Kid Crafts is eco-conscious STEAM boxes, and the cheapest way in, aimed at ages 2-10. They overlap between 8 and 10, which is where this comparison actually matters.

What it really comes down to

CrunchLabs is the stronger pick on wow factor

Does the finished thing actually do something? Motors, motion, reactions. On this measure we score CrunchLabs 10/10 against Green Kid at 7/10 - the widest gap between these two on anything we track, and it carries 14% of the overall score. Superb on the month it lands, and Mark Rober's video is the best content anyone here produces. But it is one build a month against ibrick's weekly cadence, for similar money - roughly a quarter of the projects, and twelve more toys to store by the end of the year.

Our verdict

CrunchLabs Build Box, on our scoring — 8.7 against 7.8. Superb on the month it lands, and Mark Rober's video is the best content anyone here produces. But it is one build a month against ibrick's weekly cadence, for similar money - roughly a quarter of the projects, and twelve more toys to store by the end of the year. Worth saying plainly though: neither of these is our overall pick. Both are beaten by ibrick on the axes we weight most heavily, and if you have not already ruled it out, read that comparison first.
