Great table! It was easy to put together and fits perfectly between our chase lounges on the patio. Can't wait to find a cute umbrella to go with!

Nice, but...
Size: g:Square Table with Umbrella Hole, Color: Black
Second one I bought. So I do like it, but for the price they could include an extra screw and washer. Also it would be much more convenient if the holes would line up correctly. That's why I gave only 3 stars. But it is a nice table.

Durability
I was very satisfied with the quality of another Best Choice Products: Ice Chest. So, I was happy to see the umbrella stand, weighted by water, was available by this company. It is, once again, made very resilient and strong to withstand tipping over. I'm a happy customer of this company's products!

Great design and easy to put together!
Color: Black - Square
Works very well and this is easily put together!
I filled mine with water and it is more than heavy enough to withstand a strong gust of wind. Highly recommended!

Nice base in general
Base seemed nice coming out of the box. Good size, though double check it will work for your needs as my mistake it was just a bit too big. Filled with water, it is a decent base to utilize with an umbrella I feel.
Not sure if others' bases had this, too, but mine has some kind of object rolling around the side. No way to get it out. Not sure if when the hole is drilled into the top, it's from that? Also, when filling with water, there were unpleasant fumes coming out. Water mixing with the rubber material on the inside?
All that said, for the price, this is a good option to consider for an umbrella base.
