I bought this for my 4 and 2 yr old daughters.  They love it and I was surprised at how much the 2 yr old loves to ride the rollercoaster.  Also, it is the highlight of the backyard when kids come over.  It seems to be sturdy.  I wouldn't go over the recommended weight limit though too often bc it is plastic.  This is my first winter leaving it outside.  I store the car indoors for the most part though.  

Pros: easy assembly
