My son got this as a present for his 5th birthday. It took me and my husband nearly an hour to put it together, and after less than half an hour of playing it promptly fell apart. The spinning wheels that shoot the cars around the track have no protection for little fingers either, a fact that I found extremely worrysome as little boys love to poke at their toys to see how they work. After putting the track together for probably the tenth time in a week, it went in the trash. It's flimsy, unstable, doesn't stay put together (falls apart just from the toy car going around on the track), and is not safe. Highly disappointed.
