I bought 8 shades in all and so far have had serious performance issues with 3 shades. On first use, the shades in question showed an obvious production defect. They arrived with the interior cords fashioned in such a poor manner that one side became unattached at first use. I have gotten replacements for these from Overstock with no problem at all. My only concern is that, if these shades do this in the future, I have been told that no more returns will be aurthorized. I have to wonder if these shades were overstock or factory rejects at this point. My daughter purchased the same shades from a store here and paid ten dollars less and none of hers have broken. As a result of this shoddy workmanship, my only recourse is not to move the shades unless I absolutely have to and start putting money aside to purchase future replacements at the store my daughter got her shades from.
