They are supposed to collect about a pound of sand a week.
Do you have one and do they really work?
Where did you buy it and how much are they?
The only one I can think of is the Astro Turf mat from Don Aslett's Cleaning Center. http://www.cleanreport.com/p837/Astro-Turf-Flair/product_info.html
I have them outside of both my front and back doors and I think they help a lot. The trick is getting my family to actually wipe their feet on them.
