I bought it for my 8 year old niece. She loves it!
The only problem we encountered is the setting/utilizing the password. Although she said the password, the journal did not open. It took 3 tries before it opened. She decided not to use that feature.
I LOVE this journal! The only thing is, it sometimes opens to my brothers voice. But we do sound alike! Other than that, this is perfect! The invisible ink pen works great! It has a light so that if someone does get in, my private secrets are safe! It also comes with a normal light for if it's dark. There's also a secret compartment behind the notebook to store some things. Love this journal!
