We bought this tetherball set for our 10 yr old son who loves to play tetherball at school.  Assembly was not difficult, but it was a long process filling the base with sand (which was recommended over water).  Love the portability--we didn't want to have to cement one into the ground.  The set looks sturdy, but time will tell how well it holds up.  Also, I had read in some reviews that the ball was not high quality, but for the 3 days we've had it, it is holding up well to the long hours of play my son has given it.  Overall, we are very pleased with this tetherball set.
