I gave it 5 stars due to the nice subtle colors combined with price and overall quality.  The colors are just right for me, they are not brash, and although this is a machine made rug, it looks better than many others I have seen, more subtle with variated yarn colors.  I have two real Persian rugs, and although this is clearly not that, it doesn't stick out like a sore thumb.  Its cheery, comfortable under foot (esp with rug pad), and better than I expected.
