Only one star, but would have given it none if I could. Very disappointed with this product. Second time I used it, the umbrella tipped over from the wind and the plastic piece that hold the ribs to the top of the pole snapped. I had it in a weighted base but it appears that was not enough ( my fault ). 
My complaint is the quality. With the size of the umbrella a metal connector would have possibly handled the fall better than the thin plastic.  I would not recommend this product unless they changed the top to a more secure piece.
