This the second one of theses roller coasters I have purchased. The first was 4 years ago for my grandson. It has been enjoyed, and is still being enjoyed, by younger grandchildren and their friends. It is sturdy and has held up well over the years.  When a new set of grandsons came along, I couldn't  think of a better Christmas gift for them. They love to play outside and the roller coaster is a wonderful addition to their backyard.
