hello
The good thing about the bally bands,
they keep your carpet clean.
dont forget after the dog mark its realy HARD
to get the smell of, and that alone might make the dog want to mark over and over again.
they can smell it even we think it's clean.
don't forget for the male you need to put the kotex pad inside.
i dont know how it work for the female band, never had to use one.
