I have only had the mat for a month or so but I like it really well. It is not as huge as my last mat so it's easier to move when I vaccum and the cost was much much lower than my huge mat which was much heavier and much bulkier to move when I used the sweeper. It seems to be holding up well even though I am at the computer several hours each day.
We have purchased 3 of these over 3 years or so. One cracked crumbled and disintegrated within 1 year. One is now 2 years old and another one about a year old and both are showing signs of wear. They are kind of flimsy and tend to develop indentations where a chair leg or wheel sits for any length of time making it hard to move the chair around. Never ever use any kind of chemical cleaning product -- nothing stronger than plain water or it will turn brittle and fall apart quickly! A pretty inferior product that I would NOT recommend to a friend.
