It is a nice rug and a good value, but we simply got a bad one.  After more than a month a few areas of the 9' x 12' rug never went flat to the ground (and we had a good pad under it).  These caused tripping hazards and it did shed quite a bit too.  To Wayfair's credit, they provided a full refund.  Good service and, again, just think we got one from a bad production run.  Also from reading the other reviews, it may work better in smaller versions.  As others have said, there is quite a bit of blue and it changes with the light (which I quite liked).
