I've been using an absorber chamois for over 12 years now I think.  I just bought this one within the year which replaces my last one that lasted at least 12 years.  I didn't really have to replace the old one since it was still usable but it did have a few grease stains on it that accumulated over that time.  Great value and long lasting product.  Hopefully this one lasts another 12 years!
