We have been using the stair treads on our stairs to go into the attached garage for a few days now and we are happy that they are staying in place.  The negative I found with them is when I was taking the paper off to reveal the double sided tape, the tape was coming with the paper leaving nothing on the stair treads.  I had to push the tape back on and try moving the stair treads in different ways to prevent the tape from coming off again.  Other than that we like them and our kids love (four kids ranging from one year to six years) LOVE them :)
