We purchased this rug for our kids' playroom, with the primary criteria being low price.  It's nicely made for the price, unrolled well, and doesn't have the typical unpleasant new rug smell.  While we've only had it for a few days, it appears to be durable.  Nice rubber backing, so there's no need for an anti-skid pad.  Good low pile, so that train sets and other toys can be set up without tipping over.  

Pros: Great value, fast shipping.
Cons: None
