Very happy with this umbrella so far. Read the description before buying!! It very clearly states counter weight is needed, and for the price, the additional cost to purchase counter weight is still a good deal. 
The umbrella was very easy to put together and use. It provides significant shade for our deck which has no tress  around. 
I live in the mountain dessert of Northern Arizona, so the sun is always shinning and the wind is often blowing. Two weeks after purchasing, we had three days of gusts up to 60mph. I was concerned how the umbrella would hold up, but with the added approx 200lb counter weights (also from Wayfair) the closed umbrella stayed upright. Obviously with that type of wind, I didn't try to see how it would do if opened.  I have however used the umbrella open in our regular 20-30mph wind gusts, and it's held up well.  
For this price, I would purchase again!
