I was looking for an indoor activity that my child could do during the cold season. This seemed like a fun idea and the price was the lowest that I had found online. The free next day shipping was also a plus. The roller coaster arrived on time and was so easy to put together. My two year old loves it. We can't keep him off of it. He will get plenty of exercise this winter. In the summer we will put it outside for continued fun and exercise. It's very durable and will probably last us a few years.
