We already had the original Tag reading system and when I thought my son was ready I purchased him this since it is more for his age. He became frustrated with it. I realize that the device is designed for little hands but it makes it much harder to get it on the exact word that you want because it is so big. One day my son wanted to "read" with the regular Tag system pen and he used it with ease. The books for Tag junior may be more for my son's age but he'd rather just use a regular sized pen because it works better.
