I ordered two of these panels for giant window and door at my mother's home.  The Pro's is that it is a very affordable option to cover a wide window and it does block out the light.  The Con's are the fabric is a micro-fiber so it has an institutional fee to it.  It also doesn't iron very well.  My mother didn't want to put it in the dryer because of all of the grommets hitting the inside of it.  Both panels also had black smears in and around the grommets.  We are still trying to decide if we are going to keep them or not.
