There are many amazing qualities about this umbrella. First of all, it is HUGE. The umbrella covers a very large portion of my 18 foot round pool. Second, the way you can adjust the tilt of the umbrella is a huge plus. You have to be careful about wind. I currently have blocks holding it down, but I will be bolting it to its final resting place, which will eliminate that issue. Third, it's swivels with a little foot at the bottom. This makes it so easy to adjust without moving the entire umbrella. I have not used the lights yet, however, those are a bonus feature.
