Sent it back.  Connections on frame seemed a little underbuilt for a big umbrella like this one (regular retail price of $445).  It was an open box and the box said it was mfg by California Umbrella so I thought I'd gotten the wrong one by mistake.  I called and found that even though it's sold as an Archie & Oscar brand that it's really made by California Umbrella Company.   I went to their (CA Umbrella) website and the features on the delivered umbrella were the same as one of the bottom tier umbrellas they sell.
