I absolutely LOVE this umbrella.  I was able to easily secure the platform with screws to my deck in a location that I want it in for many years to come.  I opted not to purchase the weight so that I could secure it with screws on the desk.  I can easily remove the stem of the umbrella for storage.  The was amazed at how expansive it is when it's open.  It looks so resort like.  The quality of it all the strong metal and very high quality of the fabric makes it look so nice.  When it's open it just flows with the wind and does not turn inside out like cheap umbrellas do.  It locks into the base as well and the way the umbrella is made the air just flows through it.  I am extremely satisfied and plan to purchase another soon for another spot on my large deck.
