I was very excited to receive this product. But i was extremely disappointed of the poor quality. Very easy to put together but felt very flimsy and fragile. It feels like the crank to open the umbrella will break with every turn. There is also a tiny silver plug (as seen on photo) that keeps popping out and falling each time we crank the umbrella open. 
Very cheap material. And if you live in a windy area, like myself, you will need a weighted base for sure.
