I have had a few of these Stormshield umbrellas, as two have been lost and one stolen from my workplace.
They have withstood strong winds.
My only complaint is that the handle is now narrower than on my first ones and now because of its size, it is not as comfortable to hold for long periods as you need to grip it tighter.
I assume they have done this to save a little rubber, in its construction.
I have countered this by using tennis racket grip to thicken it up.
Apart from this, it is a very good umbrella for the money.
