I had hoped to stop the creeping of a 31 foot by 26 inch carpet runner on Berber carpeting. The Miracle Hold Rug Pad has slowed the creep to make re-adjustment necessary every two to three days. Certainly an improvement over my former daily adjusting, but I will continue to look for a product that holds better. Thirty one feet causes constant flexing in the runner, so maybe there isn't a product that will be more successful.
