It's a nice rug but gave it a 3 because it's VERY thin, expensive and has a very potent odour.  If I leave my apartment and come back in all I can smell is the carpet so I have to have my air filter on.  For the price it should have its own rug pad but now have to buy one since it's so thin.  If it was thicker and $150 CAD, 4.5 stars.

Update:  I ran a small carpet cleaner on it and the entire carpet is now shrinking and will not sit flat anymore.  Cheap, do not buy.
