Okay, so I got this STEM toy set for my 6-year-old nephew, and let me tell you—it's a hit! The kid went nuts building the crane and robot first. The instructions are clear (thank goodness, because I’m not exactly an engineer), and he could mostly follow them with a little help.
PROS: 1) Keeps kids busy for HOURS. 2) Actually educational—who knew playing could teach physics? 3) Storage box is clutch (though one reviewer said theirs broke—fingers crossed ours holds up).
CONS: 1) SO. MANY. TINY. PARTS. I swear I’ve vacuumed up at least 3 mysterious pieces already. 2) Definitely not for solo 4-year-olds—more like 6+ with adult supervision unless you enjoy stepping on sharp plastic surprises.
Verdict? Worth it for the proud "I built this!" grin alone. Just maybe keep it away from pets and younger siblings.
