The Seek & Find book kept my son busy for a solid hour at the dentist's office, which never happens. The decoder wheel is sturdy enough that it hasn't broken despite being dropped twice already.

My daughter burned through all three books in one weekend, which never happens. The secret message one is her favorite since she can write notes only she and her friend can read. The seek and find pages kept her busy on a rainy afternoon too.

We grabbed this for a long road trip and the three books kept my 7-year-old quietly busy for hours. The secret message pages are her favorite part, and the decoder wheel is sturdy enough that it survived being dropped on the car floor multiple times.
