We thought this pad was fine when we bought it for our living room area rug.  However, we bought the same pad for a smaller rug, used in a high-traffic hallway and it  does not seem to be working well.  Every couple of days, we see pad sticking out from under the rug.  It seems like the pad is sticking to the hardwood floor but allowing the area rug to slide.  Next time I think I will spend more for the higher-grade pad to see if that works better
