“would recommend. my son loves it. fun to build circuits with him. wouldn’t start any earlier than age six but we are still using this at age 8. i would recommend this product.full disclosure though, a few circuit builds just didn’t work correctly. i know the build was correct to the instructions, that all connections were good (i metered them out with a Fluke multimeter) and that the batteries were new and putting out correct voltage. the problem seems to be internal to some of the modules that internal printed circuits that are inaccessible.”
