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

Wrong size
Nothing wrong with it except it was too big to fit under my table so I had to return it.

Nice quality and durable!
This works great so far. We did a mixture of sand and water. We’ve had some crazy rain and winds lately and it’s stayed put!
