The umbrella is pretty cool, and the auto-open and shut feature is handy, but it broke during a rain storm one day . Most umbrellas I wouldn't dock substantial points for this, but considering the main selling point is the wind vent, it's pretty disappointing that it didn't work. For what its worth, I don't think the wind vent ever opened. It's a neat idea, but the implementation here is shoddy.

Just be warned that if you buy it, don't expect it to work well in a windy storm (winds were about 10mph).
