Unfortunately, taking a chance I ordered these pads, only to learn they are certain to be short lived.  The material is very, very thin, therefore I will no doubt go elsewhere in the future.  I did contact the provider of this product and all I was told was to return for replacement or credit.  I was planning a trip and the steps to return, etc. were just not convenient at the time.  So, I live with these, as is, and plan to do more shopping.
