I bought 2 leapfrog toys for my 4 year old daughter and 2 1/2 year old son. Both of them are Tag Reading system. It's kind of too old for my son, but I bought the one from Tag Junior Books, and he loves it. It's great because it works on Tag Reading System. The one thing that I like this product is that you can see online of what they learned. My daughter and son really loves this toys, its perfect for everyday playing at homes, in the car. It's great in the doctor's appointment keeps them entertained while waiting.
