We added a couple of these rugs as runners in the long hallways off our entry.  I love that I could match the runner and the rugs for the door.  These have been in place about 6 months and still look like new!  They've been very durable and easy to clean.  You will need a gripper of some sort under the runners if you plan to use on hardwood floors.

Pros: Easy to clean, durable, nice colors. Available in longer lengths. 
Cons: Runners are very slippery without a runner or being anchored down with furniture.
