Loved this when it arrived.  We had to wait to use it as our pool construction was not completed but now it has been in the sun shelf of our pool (under a screen cage) for about 11 weeks and has turned into a complete mess clogging our filter basket and brand new filter and leaving "hairs" ALL OVER.  The price of the umbrella was actually more than most so I made the assumption it would last.  WRONG!!!!
