I have this Cars 2 learning Renner for my four year old son bestellt.Er is extremely enthusiastic and I am, too. There are car racing where you have to dodge the oncoming cars, on several race tracks, games to learn the numbers and counting, games to learn the sound and appearance of the letters. And even if my son can already count to 20, so the learning Renner is a nice way to also learn the appearance of numbers that he is not all recognize. It makes him great fun and I think this device at the price of 19.99 new, with very good Lernprog
