I had dark rugs in a room with dark furniture with no window, and the room was always dark, no matter how much light I tried to put in there.  This was much less expensive than my old rugs, but mad a HUGE difference in the room.  A single light over the dining table looks great. Or I can turn all the lights on and it sparkles. It's lightweight. It was even easy to install even with the heavy dining table. The curling at the end didn't take that long to stop just using some heavy objects on it. Liked it so well, I got another for the kitchen and one for the hall. 

Pros: Fun, modern geometric pattern that wakes up the room and compliments other rugs in my house. Didn't hurt the pocketbook.
Cons: So far so good.
