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.

The umbrella stand works .
The umbrella stand when filled with water is not as study as I like.

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.

Great weight
Very easy to put together and fill with water. Strong winds today and so far so good without a table to support it. If I need to I can add sand later. I wish I had one of these years ago

Perfec
Nice I used this as a replacement to something else I had: the other thing was too bulky so this was a perfect fit under the table gives more room
