I bought two of these shades for my guestroom. 
Installation was pretty straight forward, tho I did end up with a couple of extra pieces (oops).
The blinds seem sturdy, well made and glide as easily as the name suggests.
They provide privacy and keep the harsh afternoon sun out, tho they are by no means light blocking or room darkening. If that is what you are looking for, then you will have to go with a different product.
However, they serve their intended purpose well and are attractive enough.
I will be buying more soon.
