Cost Effective Good Weighted Base
Size: 1-Piece, Color: Black, Size: 1-Piece, Color: Black
Strong metal pole to hold the umbrella and thick plastic base that feels very well made. Very simple to put together with the provided allen-wrench, just took time to make sure it was very tight. Got it for my neighbor's umbrella. Make sure you have it where you want it before filling it. It is unfilled at the moment and yet still has helped the umbrella stay stable. I like the look of it and that it can be used with or without a table. I really like the idea that if you have another long pole items that it can be used for those as well. The double lock design is a nice feature. Inexpensive.

Purple Purple!!
Size: 9ft, Color: Dark Purple, Size: 9ft, Color: Dark Purple
Looks great!! I would say the color is like Crayola marker purple. It was easy to assemble straight out of the box. And a perfect size for my six person patio table. The weight of the fabric seems of high-quality and thickness. I would recommend as it seems to be a good value for the price point..

Vibrant backyard umbrella
Size: 9ft, Color: Lake Blue
The umbrella does its job, it tilts so you can position the umbrella to block the sun at all hours. The colors are vibrant and fabric is decent quality, I bought the turquoise this time and dark blue in the past, the fabric keeps cleans. The umbrella isn't heavy, easy to maneuver. This was a replacement for our previous umbrella which broke at the tilt joint, after a very windy day when we forgot to close it, but it lasted over a year and a half so no complaints there.

Nice Umbrella for the Price
Size: 9ft, Color: Red
Truly surprised at the quality of this umbrella. Great deal for the price. I did see some reviews prior to buying that there were issues with the tilting mechanism/crank so I am giving it a 4 until I have it for more than a few days to see how it all works out.
