These foam mats were always moving out of position on my kitchen floor. I had tried other ways to secure them but none strong enuf to do the job. These were easy to apply and did the job. Haven't needed to clean and re-secure yet. But, by the way they are designed, I do not anticipate a problem. Definitely glad I bought them.
