Very easy to use. My 2 year old daughter loves hers.
She has the Thomas book for it and is always on it. I had to start putting rechargeable battries in it she uses it so much.
Love that it comes in a backpack that has segments for all the books and cartridges to neatly go in.
Love that it is still an electronic game but limits screen time as its still a book.
Fantastic learning toy for toddlers/pre-schoolers can't recommend enough
