Materials that constitute it are of good quality and finish seems to be good too. I didn't had the opportunity yet to test it in harsh conditions and high frequent use. About the 56 inch; diameter, I've measured it. What they call 56 inch; diameter is actually it circumference. It is the length of the diametral circumference. The diameter itself under the plane covered by the umbrella is about 50 inch, not 56 inch as advertised. Still, it has enough space for two.
