These shades look good and do a good job of reducing the heat comming through our sliding glass doors.  I mounted two four foot shades side by side so one could be openned a couple of feet to let the dog in and out.  I mounted them so they roll down next to the wall so the wind wouldn't blow them around and am happy with them.  They are easy to mount and I would reccomend them to anyone who wants to lower HVAC bills.
