I love it, and intend to keep it. I can't accuse you of false advertising because the description was clear that it accepted umbrella poles up to 1" diameter. I should have done my homework. As of today, I have not found an umbrella with a pole less than 1-1/2". I've decided to purchase an umbrella of my choice, with no consideration of diameter of the pole. Then I will increase the size of the hole in the base with a grinder or sander. It's made of good sturdy plastic and should be able to withstand the pressure of a grinder. If not, I tried. And the price was very reasonable so I will not ask for a refund if it cracks or breaks!
