Pro's: Easy to set up. Has a case to put the car in.
Con's: #1...BATTERIES, they will be expensive to replace. They are little watch batteries. I would rather see something rechargable. #2...Only rolls on a hard surface. Limited playability.
#3....They offer about 5 minutes of interest to my 5 year old boy. Even less for my 7 year old boy.
You can get bigger cars that alleviate these concerns for the same price or a little more.
