It is very good, provided that an adult will engage and narrate the images/have a dialogue with the child. The projector works perfectly, we project it on the ceiling before bedtime and the images appear very clear in a large size. Each disc has 8 very beautiful drawings that do not repeat. It also includes 3 booklets with wonderful illustrations for familiarizing with animals and the explorer's activities. I only disagree with the price, I think it could cost less, especially when compared proportionally to larger packages that have 32 discs. There is a possibility that you may need to replace the batteries before the first use, but I think it has to do with the store and not the product.
