Reusable Dryer Sheets

As much as I love my Bounce dryer sheets, they sure are a lot of waste! So I was curious when I saw these...has anyone tried them?

From the May 2010 issue of Real Simple magazine:
Reusable Dryer Sheet
"The eco-friendly, hypoallergenic Static Eliminator reduces cling and softens fabric just like traditional dryer sheets but without cluttering up your trash can. Each cloth withstands hundreds of loads. TO BUY: $15 for two, amazon.com
