This stand is very well made. It has protective tabs so the screw does not go into the pole, it comes with two of the plastic rings that go at the top of this base (each one for a different size pole), AND it is so heavy, it probably won't ever flip over. In saying that, my umbrella has already flipped over right after I put it out on my deck. I am really thinking that the pole (that comes with the umbrella is not well made and sturdy enough to hold the umbrella in the stand. I will be researching that next.
