Customers say
Customers find this science kit to be a great starter set that provides hours of entertainment and is particularly enjoyable for 9-year-old boys. Moreover, they appreciate its educational value, with one customer noting it’s suitable for sixth-grade projects, and its easy-to-follow instructions. However, the functionality and magnet strength receive mixed reviews – while some say it works great, others report it doesn’t work at all, and while the magnets are perfect for teaching about magnetic force, some find them weak. Additionally, customers express concerns about the size of the kit, mentioning it’s smaller than expected and contains many very small pieces.
