This half round umbrella stand is half-a**. In my opinion its not worth half what I paid for it.  Look at the picture and you can see it doesnt even come half way close to keeping the umbrella pole straight. I made sure I didnt only half-way tighten the lone bolt underneath and the upper screw that can be visibly seen that screws directly into the umbrella. I got this stand back in April, and while it never did keep the umbrella completely straight, I noticed half way through summer it was getting progressively worse. In all seriousness Im not speaking in half truths.  Believe me, you havent heard the half of it. Anyway, I cant spend half my day writing this review. Its half past the hour and Ive got to go. Half a good day!
