Santa set this up in our living room and it was by far the favorite gift of the day.  Our 5 y.o. and 2y.o. are still riding it morning, noon, and night.  Just high enough to be thrilling yet low enough to be safe.  The notches up top to hold the coaster in place are perfect.  This coaster is well designed and will clearly provide hours of fun for years to come. My big kids (14y.o.ds, 12 y.o. dd) were jealous!
