I would give this average.  I came to put the tubes together to find they were all bent oval - my husband was able to straighten so we got the pole together.  Feels sturdy in ground and I like that the in ground spike is long so it definitely doesn’t rock around a lot. Started playing however and perhaps we are too strong (!) and ball came apart from the tether.  We never had this issue with our prior swingball set.  We have repaired and it works fine with kids but if like us you are big kids at heart this will need you to buy a stronger tether. All in all tho it’s decent but not without some challenges!
