SCHRLING Blackout Roller Shades - Thermal Insulated No Drill Room Darkening Window Blinds, Custom Size 36" W x 64" L in Ecru | Perfect for Bedrooms, Home Theaters & Nursery Light Control

My inset window measured precisely 36W X 58 1/2H. Since there are already blinds installed on the inset, I wanted the shade to go from above the window on the outside, to fully block the light on summer morning's on this eastern-facing bedroom window. Although the site recommended that, for an exterior hang, two extra inches on either side was needed, I decided to go with the standard, non-custom width, and the 60 inch length provided the extra needed to reach the bottom of the window from above the inset. I did not mind a tiny strip of light at either side of the shade. The shade's light-blocking ability is excellent. It rolls very smoothly. I would have given it five stars but for two tiny problems: First, the cord clip. The clip is plastic, and if there is a trick to bending the hard clip outward so that one can slip the plastic beads of the chain into the prong, well, I'm not smart enough to figure it out, and the "illiterate" instructions (pictures only, no words) certainly do not make this clear. The second problem is that, not wanting to attempt drilling into the hard wall framing around my inset window, I decided to use the provided sticky tabs to install the shade. There are only four of these in the package. Although the shade is very light, I still doubted that would be enough, and I was correct; only 48 hours later, the shade fell off the window in the middle of the night, scaring the (bad word deleted) out of me! In retrospect, it's a good thing the cord wasn't inserted in the cord clip, for the chain would have broken when this happened. Anyway, I purchased a full package of sticky tabs to cover the entire head of the shade and re-installed it. Nevertheless, I like the shade well enough that I have now also ordered them for my western-facing windows (same problem with the summer sun).
