I have had this pad for 5 months. It is on a Hand scraped Hickory, engineered wood floor. I ordered a 9x13 rug and three 2x10 runners for the hallway. I purchased this pad in a 11-6 x 14-6. I cut the large area rug piece and laid it with my area rug in the dinning room. With a heavy table on the rug it goes no where and performs well.   I then cut two runners from the side and one from the end. All seemed great. The runners are NEVER in place. Weather it is me or my large dogs walking on the rugs they travel off the pad constantly (4" a day)!  It is very frustrating!  Would only recommend for a dinning room or where a heavy object will keep the rug in place.
