Haven't had this very long so it remains to be seen if it will hold up to everyday use. It does dent quite easily from the rollers but so far it's not hard to change position a little. I think the softness will keep it from cracking however. It's definitely keeping the carpet in front of my computer clear from crumbs which is mainly why I bought it.
The last mats we ordered lasted about a year then cracked and pieces started breaking out. These new mats do not have the grip on the bottom and they slide all over.
This item should be rolled rather than folded. It took one week for the folds to lay flat. I am concerned about the folds becoming weak spots and cracking prematurely.
