My 3 year old granddaughter is having the time of her life riding this coaster and then pushing it back to the top.  She is thrilled that she can manage it totally on her own.  I am sure it will provide her with many years of enjoyment.  I could not have chosen a better gift. 

Pros: Easy assembly, durable, easy for a child to manage, safe, provides healthy exercise along with fun
Cons: Requires space for coaster and then more space to get maximum ride so it may be a problem for indoor  play
