I have the Beba and I adore it!! It's three years old now and still "brand new". It's the translucent kind.
The "green" type mats I had to "take care" of at least once a year ... scrape it with the edge of my ruler and put warm wet towels on it to get rid of the cut marks.
The Beba mat ... I run a damp rag over it every now and then if I think it's it's dusty or dirty.
