Bought these to help my elderly dog, but they are pretty useless. Too lightweight, and not quality. After a month the sticky on the back had come unstuck from the rugs, so now they slip around, but the sticky is still super stuck to my floors. Going to have to spend half a day scraping the sticky off my wood stairs. Wish I could return or be reimbursed.....but of course I am now out of the return window.
