The umbrella itself is awesome - good size, easy to assemble, pedal to rotate, easy to open.  The BIG drawback is the base it comes with is not sufficient to support the umbrella.  We even built a base out of plywood (as recommended in the in-package instructions, but not on the website) but need to bolt it to the concrete.  We will need to spend more money to buy a base.  Buyers should be advised that a separate, additional base is essential or the umbrella will take off.
