Nice umbrella stand
This stand is sturdy enough for my 9 ft umbrella. I only used water to fill it so it can be moved if necessary. The umbrella is taken down if it gets too windy as it would be damaged. This would not be the fault of the stand, just the nature of living near the coast.

Umbrella base
This umbrella base comes with a hole in it, in order for you to put sand in / water. You could get water in it a lot easier than you could sand. There's a tiny hole and the sand does not go very well down that hole. I've had a hard time trying to get the sand in. It is round in shape which makes it easier in the wind to tip over. But all in all for the price it was okay.
