Tips over with the slightest wind even though we filled the base with water AND stacked to huge paver bricks on it.  The directions (not) for this item are TERRIBLE.  Pictures and numbers without any instructions aren't enough.  The knobs and crank are cheap plastic and won't last long.  Nothing included to hold the umbrella together when it's down and it flaps and slams agains the base.  WASTE OF MONEY!!!
