We've had this umbrella for just over a year, only really using it for one summer, and the umbrella won't open. The cord came untied inside the reel after a few months, then, after pulling it apart to fix it, the hardware inside the reel snapped and is no longer repairable. 
The umbrella blows around excessively in any wind, even just a breeze, so we only got limited use out of the umbrella while we had it as we could only use it on days that were almost completely still.
I would not recommend this product as the design is flawed and the construction quality is low.
