I bought (2) of these carpets, one for each of my boys rooms.  I wanted a charcoal, dark gray rug and this looked like it would fit the bill. The carpets feel amazing, I love stepping on them.  I did not give it 5 stars just because it is definitely not all gray, mine arrived black and gray.  If you really need/want it to be one solid color then this may not work for you but if you can work with the black mix then it's a great rug.  

Pros: Great quality, very plush, arrived quicker than anticipated
Cons: Not a solid gray color
