I am pretty happy with these rugs I ordered.  I like that they have the rubber backing so they stay in place.  I ordered the two different sized area rugs and the runner.  The color tone is a bit darker on the smaller area rug and the runner compared to the larger area rug but I have them placed far enough away from each other that it isn't noticeable.  For the price - I am happy.  

Pros: they stay put because of the rubber backing and they vacuum up nicely.
Cons: slight difference in the color tone but not a real issue for me because of placement.
