USELESS WITH JAELYNN CANTILEVER UMBRELLA. I purchased the Duncombe umbrella base since it was listed as combo item with the Jaelynn 9.5 Cantilever Umbrella. The base doesnt fit into the bottom stand of the umbrella - the screw lid is too big to fit within the bottom making this base virtually useless together with the umbrella. Also I had to put one of the four bases on top of two to add weight as I dont trust the small bottom edge (1-1.5 inch) to carry the weight of the suspended umbrella in the wind.
