There has been lots of rain in this area since I recieved this umbrella.  After reading the various reviews, I can only guess there is big variation in quality control.  Mine has no problems at all. I has been used many times and has always worked well for me.  It is BIG, and I like that.  The color of the canopy is not the usual black so it is easy to identify on a rack with others.  Also, it has more spines than is typical for umbrellas of this size.  It think that gives it better strength.  The description says it is teflon coated.  I cannot varify that, but it does dry very quickly. All this has made it the one I reach for all the time.  I have a Tumi folder that I really like, but it stays in my bag now, for use when I am unprepared.  My only quibble, keeping it from 5 stars, is what is the handle material?
It looks at first, from color and grain structure, to be birch or some similar wood.
But the finish chips off easily and underneath is something white with no grain structure at all.
