My dad & I are on the older end of customers (20+yrs) but our 1st time building electronics went great thanks to the well detailed packaging & instructions! The science explanations, history, & drawings were implemented in a fun way too :) I only ran into 1 issue where it was hard to tell which blue wire had the black stripe, so I checked the other wires & noticed the ones without a stripe had numbers so I used that as an indicator.

One of my son’s favorite projects! And very functional - he takes it with him to bed. Lesson plan was at the right level to keep him interested.

I would say it was hard but it is really cool. I find lego parts with it. The writing was hard. But we finally got it.
