I have only had the set for about a week but I love it.  We had very high winds yesterday and the chairs moved around a bit but all in all everything stayed put.  Better directions should be included as it took 6 people several hours of trying to figure out which bolts go where.  A couple holes did not line up, a clasp does not line up and one bag of small bolts and washers was missing.  Other than that, the set looks amazing and is very comfortable.  For the price, I am very happy.

Pros: Great value and looks amazing.
Cons: Needs better directions and to make sure all the holes line up correctly.
