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.
I used a very nice coupon that gave me $10 off each chairmat plus an overall $5 off for a purchase of over $30. I bought 5 mats so this gave me $11 off each one. Great price for a good value.
