My son has grown up with Leap Frog products. We fell in love with the first product we introduced him to when he was a baby. We have used the toddler leap pad, the leap pad, and several leapsters. Now, he has had his Tag for over a year and enjoyed it immensely! We have an entire library of books and additional activities to use with it. My son loves to have books read to him, these are great because not only do they read a story to him but, there are additional learning games in the back of each book! He loves his Tag so much that he has memorized several of the stories in some of his books! Cons: My only problem with it is the limited amount of space on it. After a period of time, I have to transfer off books he is tired of and replace books he hasn't had on it for a while. We have so many books, it would probably be easier to have two Tag Readers but, then he would have the problem of which book belongs to which Tag. I also wish it would work with an adapter. I don't know if it will but, we haven't been able to figure out how to hook it up.
