My 3yr old grandson loves this and is able to use it by himself. Mobigo is a great system and has lasted very well as this was his elder brother's - we've just added to the games over time. Educational in a fun way for the tinies.
My boy (5) loves this. I was concerned that he might be a bit too old for it but he loves it and plays happily with it regularly. Works with Mobigo1 (for anyone who is concerned about compatibility) and has a variety of games mini-games to choose from. It looks a lot better than the Cars game that shipped with the console.
