We have several Coolaroo shades and have always appreciated the great quality of the product.  The roller shades we just purchased are beautiful and fit our patio very nicely.  We especially like the tie-downs as we have windy conditions.  The only downfall is the wand system to roll the shade up and down is cumbersome.  In a sudden wind storm situation, I had to struggle to get the shade rolled up.  The chain system on some of our other shades is a much faster way to roll the shade up and down quickly, although I understand the safety factor of a chain dangling down.
