This is a nice umbrella with LED lighting inside the spine of the umbrella.  The overhang does make the positioning slightly awkward but once the position is established it works well.  The base does need support, especially if there is any wind.  Instructions show to put the base feet under pavers, however I ended up using a PVC tube attached to the deck and slid the umbrella base into this.  It worked but then decided to put the tube in a large planter, filled it with quick-create and used that.  It provided a 100# base but still movable.  The one thing that would make it five stars is that if the position while open could be tilted or adjusted to angle the cover.  That is fixed and not adjustable, otherwise it is very nice item.
