My son who is crazy about cars absolutely loves this toy. I bought it for him at age 3 thinking that he was a bit old for this type of game but he was hooked immediately and played for 15 minutes at a time without getting bored. Although I have tried different methods of teaching him numbers, this is the one which stuck. Its also good for hand-eye coordination as you do need to concentrate in order to grab the cars using the truck magnet. The only slight issue I found is that the numbers are not written inside the spaces so it was tricky to find out which car fit into which space. I overcame this by writing the numbers in myself. This product is so beautifully made that I can see it lasting for a looong time - as long as we don't lose the pieces!
