Why is NorthCape International outdoor furniture not good for outdoor use?

The ads say “Extend your lifestyle outdoors”.
“Synthetic resin materials are made to withstand the elements.”

However, their warranty for the Premium Grade product Mackinac Collection says: “The frame is warranted for 7 years except if it is damaged due to exposure to water.” “The Resin Wicker is warranted for a period of 3 years against separation cracking tearing except for exposure to sunlight or natural elements.” There are similar limitations for the fabric and cushions.
Does this sound like an outdoor product? If it cannot be used in sunlight and cannot be used in a place where it might get wet how can they call this an outdoor product?
There are other basic quality issues. The rocker runners are plastic and are not flat against the floor. They are tilted at odd angles and are screwed to the legs with conventional screws that extend and scratch the floor when you rock or move the chair.

I went to local furniture store and was willing to pay more for something locally made. It turns out that only the cushion cover was local. Everything else was Made in china. I was foolish enough to pay $399 each thinking I was supporting local industry. If these were purchased for $75 I would not complain. You get what you pay for. But, this NCI stuff is shameful junk.

Is this false advertising? Would you take the chairs back? Would you start a FB page and include photos of the bad design and poor workmanship? Would you just tell everyone you know to avoid this place and that NCI furniture is junk? What outdoor furniture do you use?
