This base is great for the price and it looks very nice.  I bought it for a 11' Market Umbrella.  It has a wide opening in the base so it fits this larger size pole, but it isn't snug and the pin that holds the pole in place kept moving around when the slightest breeze would come along and then my umbrella would swing around.  I'm trying to stuff rocks inside so it won't have any place to move.

Pros: Great finish, holds lots of sand for heavy weight.
Cons: Small spout to fill the sand is on the side, not top, so it makes it difficult to fill.
