These sliding shades were an elegant solution to a problem patio door bounded by baseboard heating, as well as an odd-shaped room with oversized furniture.

The minimal style and modest intrusion into to room seem to work well.  We could tailor the width and height to an exact fit without impairing the radiant heating.

But we have to dock one star for truly bad hardware and instructions.  The illustrations show use of a 5/16" drill for installation on drywall.  The cheap plastic screw anchors (maybe 1/4"?) went right through the 5/16" holes, necessitating a trip to buy 3/8" Pop-Toggles.  Once we got that out of the way, the installation was mostly straightforward.  

These shades aren't terrifically sturdy - there's a lot of flex in the mounting rails. I wouldn't plan on using them in a high-traffic area, but they do look sleek and provide enough shade for guest sleepovers.
