Great product, I had a small issue with on the the arms on a very stormy day 3 years later but the Customer service was excellent and helped me replace it due to damage. It's small portable and works excellent.  The open close button is very reliable and extremely convenient.  It would be nice if it was 2 layered and allowed the wind to pass through as it will invert in very heavy wind but it flips back right away and seems designed to handle it.
