Awesome STEM kit with tons of projects

This YCFUN science kit is a huge hit in our house. The 420 projects keep my kids busy and actually learning — everything from simple circuits to more advanced experiments. The parts are sturdy, the instructions are clear, and it's fun for a wide age range. Great hands-on STEM toy that makes science exciting. Highly recommend!

Great set for kids

This set exceeded my expectations. My oldest son loves circuit sets, but the one he has is too difficult for my younger son so I was trying to find a simpler one. This one is easier to connect so I think he will be able to do it on his own. This set has many features that I know both boys are going to love. I feel like a lot of the sets have repetitive pieces, but this one seemed more unique so I can see his older brother wanting to use it as well.
