This is the second time I have purchased gel pro mats. My first order of the classic mats was 9 years ago when we built our home. While the edges were curling a bit- they were still working well. When we moved to our new home- I purchased the New Life mats (new color to match our new kitchen). They are even better than the original mats! Love them! Of course, we are recycling our old classic mats to our son and daughter in law for their home.
