We purchased this particular umbrella to put beside our spa because of the offset pole.  The desert can be a scorcher, and we can adjust this cantilever umbrella to sit in the spa but OUT OF THE SUN.  We put the four crossbar base feet through concrete building blocks and dug it down into the dirt to cover the blocks.  It is now very sturdy and has no problems with blowing over in the winds.  

Pros: Very nice looking and does the job!
