Nice shade however all the pics show their inside mount rollers shades material is flush with the window edge. This is NOT the case. There will be a 1.5 inch gap between the material and the window. The instructions do mention this, but the pictures don't show this.

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 1 to 1 1/4 inch (1 1/4 inch for the Deluxe products) less than the ordered width. 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.
So, with an inside mount roller shade the gaps are absolutely essential. You can mount outside the window to cover the window opening completely.
