We are really happy with both books. My 11 month grandson was immediately fascinated by the buttons, switches and lights. My engineer son loved it as well. When it arrived, I did have to email Chase as it didn’t work. Chase emailed back promptly with troubleshooting. That’s when I discovered that the books didn’t have any batteries. I placed a no. 2025 button battery in each and it worked perfectly.

As an electrical engineer I really like these books. My babyboy is just 3 months old now, but I hope he will like the books too when he will be older. :)

I got my books in short order and thoroughly enjoy playing with the circuit buttons and switches. Though, I really want a full adder circuit (book3?)
