The umbrella has been great to keep the western sun at bay in the afternoon on our deck.  The ability to tilt gives us a few more hours of usable time each day.  The only issue I have is that the wind can sometimes turn it towards the house and the fabric hits the brick siding.  It has some play with how much it can 'twist' can I guess I just have to figure out some way of eliminating the play before I put it out again this year.
