The shade was too narrow. No effort to help from your customer service.
Poor customer service.
Response from Blindster
I'm sorry you weren't happy with your roller shades. All window coverings that are mounted inside the window should be ordered using the actual window opening width (for roller shades use only the width at the top of the window). The top of a roller (outside bracket to outside bracket) is the widest point of the shade and is made just slightly smaller (1/4 inch deduction for this product but it varies by factory).
The fabric will actually be made between 7/8 inch and 1 1/2 inch inch less than the ordered width (on this particular shade it is 1 1/8 inch). This deduction is necessary because the operating components must fit onto the end of the tube. In addition, the fabric can't be wider than the tube or the mechanisms will damage the fabric.
You could have had this shade remade under our Fit or Free Policy to a new width or as an outside mount so your fabric can be wider. We pay for the replacement shade, you pay $15 for the shipping plus the price difference (if any) if the new shade costs more than the original shade.
However, when reviewing your order, you chose to return the shade under our Satisfaction Guarantee and we have process a refund.
