I had the original gel pro mats for 6 years. It was time for an upgrade as the edges were rolling and they were getting cracked tops. I decided elite was a good choice and I’m so glad I did!  The angled edges will not roll like the others and the different material suggests that the tops will not crack. They feel so wonderful under my feet!  The extra cushion is heavenly. My only concern is that they do seem to move around a bit more on the floor than my older ones did. Not by much, just a few inches each day I have to move them back to their place (they are on hardwood floor)
