Free shipping is always a huge plus and it did ship in a timely manner, right to my door and was packaged very securely.
It appears to be of excellent materials and putting it together was not a problem for me even though I'm getting along in years.  The instructions were easy to follow and the all the hardware was included.....even a few extra parts packaged which is not too common.
All we had to do was add 750 pounds of brown sand (good for road building and castle making) and the Grandkids had a great ending to their Memorial week-end.  
We're so impressed that we're thinking of buying a few more for our children to have at their homes.
