First, it is not close to 10'.  It measures 8.5' at best.  The top was damaged upon delivery and the cheap plastic support for the heavy canvas and pole are already showing signs of stress. The expensive add-on-base (which is absolutely needed for this umbrella) does not fit around the weak original stand. Additionally, the 4 metal "clamps" to keep the base together are comically too small to fit the holes and are virtuously useless. I sincerely regret this purchase.
