Well made & sturdy
Size: 6.5x10ft, Color: Red
I have it in the umbrella stand however I haven’t used it yet as it hasn’t been sunny where I live.
Once I begin to use it, I’ll update this review.

Horrible quality
Size: 6.5x10ft, Color: Red
Horrible quality. The crank didn't work. The umbrella just flopped open. Once it did I cranked it, but it was cranking in wrong direction. Umbrella sat totally lopsided. The overall quality of this umbrella including the canopy is junk. Looks cheap. Returning!!
