I acquired a couple of these LeapPad Learning Systems at garage sales and my children love them! They're easy enough to use that my children (ages 4 and 2) can operate them by themselves. My two-year-old needs help changing cartridges, but I'm happy to that (or have his big sister help). He's also grown in his abilities. When he first received his LeapPad, he didn't do much more than jab the pointer at it. Now he understands how to push the green circle on each page and to play a few of the games. I love that he's learning, on his own, how to make things work and answering questions in the game. Meanwhile, our four-year-old regularly pulls out the little books, switching between books and cartridges easily. She can play through the books entirely on her own, playing the games, answering the questions and following the spoken instructions. They both LOVE them. I would highly recommend these systems for anyone.
