Query: Must-have item

Great product, great sound, light, the renditions of each "nature's state" have a pure sound. I don't have a favorite, my child sleeps well with either one of them. I bought the other version of the product with image projection thinking to keep one and return the other. I ended up keeping them both: one I keep in the crib and the other one in whatever woom my child wants to take a nap. The images are cute, with the sun smiling and the octapod of the sea is simply adorable! I recommend both products!
