Good buy
Size: 21.26in
This one’s a good buy. Great stability during a breezy day. It’s good quality metal, with a good shape helping stability I think. Would’ve given 5 stars if it had 360 wheel turning. I filled with water & 50lbs sand - using a funnel for the sand helped speeding up the sand.

Versitile system, easy to install.
Good system. No more tools leaning against the garage wall and blocking the door sensor.

Easy to use & provide great light!
I bought two lights for our patio. I love them. They have low and high light settings, which is wonderful. They're easily attached to the umbrella! I was pleased with the quality.
