Washable Underpads Washable Puppy Pads, Any Pros?

Washable Puppy Pads, any Pros? - washable underpads

I recently met MedNet Washable Puppy Pads (http://www.mednetdirect.com/Sofnit-Washa ... that sell for $ 130/24pk. I am not an advocate of the use of these tablets unless slowly (during 4-5 weeks training will be used) or sick dogs, people or immobile elderly people, but wondered what are the advantages of such a thing. It seems possible to spend $ 130 on diapers reusable simple.

Thoughts?
