We purchased the whole set for our grandson for Christmas. We have a couple here and they are great!

My 10 year old loves listening to these in the car. At first he said he thought they would be lame. Then after listening to a few minutes of the first one, he's hurrying me each time we get in the car to turn on the next segment. He even complains when it's time to turn off the car. I'm really glad I got them.
