I work in New Haven CT, and in the fall, and winter the wind comes right off the water, so I'm always in the market for an umbrella that will last for a couple of years. I learned from experience, that there is no such thing as an umbrella that can stand up to 50 mph. Most good quality umbrellas can't stand up to winds 20 mph. What I'm looking for is a strong auto open/close, and can stand up to heavy rains. This umbrella is very good quality, with a strong open/close button. I will update when needed, as of now I'm very happy with my purchase. Update: 6/11/18. I've used this a few times now, and the inside is starting to rust. I have never had an umbrella do this.
