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.

Sturdy, Reliable, and Visually Pleasing - A Must-Have Patio Accessory!
I recently purchased the Best Choice Products 55lb Capacity Fillable Umbrella Base Stand for my backyard patio, and I have to say, I'm absolutely thrilled with this purchase. This umbrella stand has quickly become a reliable and crucial part of our outdoor setup.
To start off, the assembly was straightforward and didn't take up much time. The instructions were clear, easy to understand, and within minutes we were able to get it set up. No additional tools or complex steps were necessary, which was a great relief as I'm not exactly a DIY person.
I filled it with sand, which brought it to its maximum capacity of 55lbs, and the stability it provides is exceptional. We've had several windy days since I've purchased the stand, and not once has my patio umbrella tilted or tipped. The 2 adjustment knobs on the sides help to secure the umbrella pole firmly, which provides an additional layer of stability.
The stand's faux wicker design is another aspect I absolutely love. It beautifully complements my other patio furniture and adds a touch of sophistication to my outdoor decor. The plastic used for the stand is of high quality and convincingly mimics the look of real wicker without the associated maintenance or weathering concerns.
Being a round base, it conveniently fits in our patio corner without taking up too much space. Moreover, it's been outside in various weather conditions - from intense sun to rain showers - and it hasn't shown any signs of wear or color fading. The material seems durable and capable of withstanding different weather patterns, which is exactly what I needed.
Also, despite being sturdy and heavy when filled, the base is easy to move around when empty. This makes it convenient to store away during the winter or rearrange when we want to change up our patio layout.

Good stand but has issues.
Color: Black - Sunburst
Very sturdy and looks good. But, the part that holds the umbrella is loose and requires a wedge to stop it spinning (I used a plastic knife). Also the screw on the bottom RUSTS and in a BIG way. To solve the rust issue I put an old plastic cutting board under it. We use it with the modifications mentioned.
