The base is very attractive, but the stem part that holds the umbrella would make the connection more stable if it were taller.  Also, the listing on the website did not state that there was a limitation for the size of the umbrella or that it shouldn't be used as a standalone base. Maybe they all say this because of liability. Anyway, I considered returning it but it would be a big hassle because it is so heavy. And it would cost a lot.
