Bought this for the kids to play in the backyard during this covid time.  They love it! Ages 5, 5, and 4.  Putting it together took two solid hours with two adults helping.  My only complaint at this time is that the caps for the screwbolts break off easily but thats knit-picking. Overall its sturdy and fun for the kids, even I swing on the saucer disc with the kids. Great investment!
