Anyone used COOLAROO Outdoor blinds?

I am looking at purchasing some outdoor blinds for a deck area - for shade and also privacy. I don't want the clear or tinted bistro PVC type blinds and have been looking at the shade cloth type ones. COOLAROO brand that i have looked at in Bunnings seem to fit the bill in looks, sizing and price but i wondered if anyone had them and cared to comment? In particular I want to some how secure them down (they wont be flat against a window as i think they are intended for) and i don't want them banging around in the wind.
