I wanted something abstract and with blue and gray. This fit the bill perfectly.  I was worried that the pattern would not look good at the large rug size - it's so hard to tell from a picture - but it looks great and ties the room together..

Pros: It's soft underfoot.  Flattened easily.  It had very little 'new rug' smell and what little there was dissipated completely in just a day or two
Cons: None that I can see.  I think would feel a little thin if it was by itself but as I have it layered over a wall-to-wall carpet, that is not an issue for me.
