I cannot say enough great things about this product. I have an autistic son, and this V.Reader taught him to read when he was just two years old! He had a lot of trouble with communication, and none of his toys seemed to interest him. I bought this for him because he liked computers, and he was instantly hooked. It comes with a few free books to download, and you can buy additional ones online or in stores. It also has games that come with each book. When a story is being read to the child, it highlights each word as it says it so the child can follow along. Each cartridge has an age range associated with it so you can find the ones that will be best for your child. My son had this for about two months, and then he was reading simple two and three letter words. It wasn't long before my son was reading longer words because he had learned to sound out the words. My son learning to read was the first step on his way to learning to communicate, and I am forever grateful for this product. I tell every parents I meet to buy on of these!
