We got these to replace our old blinds in our master bedroom.  They are wonderful!  They were super easy to install and I love all the available options available for the sizes.  They are everything the description said they were and more.  Definitely room darkening and they seem to be insulated and that was incredibly fantastic during this years polar vortex. I love the fact that there are no strings and you can just adjust them by moving them up and down with your hand.  I was a little skeptical about ordering blinds on line but I am very glad I did!!
