The screw that hold every section together rust when they get wet. It drips down and creates rust spots on my deck. On many occasions I needed to scrub a number of times to get my deck cleaned. 
When I put the various section away for the winter (yesterday) the rust on all the sections created a trail of rust stains. 
The furniture is well made and good looking - however, using rustproof screws would be the smart way to go. 
I was going to add additional pieces to our 2 set, but doubt I will use farrish again.
