I was a little hesitant about purchasing because I saw a lot of reviews that said they did not stick well. I made sure my stairs were cleaned prior to laying them. They have been on for two weeks and I have vacuumed them by hand every other day since then. I’ve had no issues whatsoever. I did purchase some carpet tape to put on the backing when they do start to move and lose their grip. For the price I am very, very happy with them. ￼
