I've had this umbrella for about 2 months, and have used it during the recent stormy Californian weather. The Teflon coating works well to repel water (though not 100% effective, as droplets still linger even after a hard shake) and the size is good enough for 2 people. The one-button open and close is great and it folds to a decent size, though heavier than some cheaper umbrellas.
However, the way the ribs are designed, with a \"U\" shape rather than a solid rod, makes them easily broken. One of them on mine just broke after colliding with a doorway with hardly any force. It's still usable, but I expected a little more for $23 umbrella.
