Not to put anything to rest (why would we?), but it seems every online discussion I have followed about e-collars (here and elsewhere) follows a fixed script:people who are against describe e-collars as cruel, no matter the particular application or dog; people who use them can argue all they want, but they are viewed as lazy at best, dumb and mean at worst.
It's a pity.
And as to eeeefarm: I really don't see how she is selling something here; she is describing her own experiences, assesses some of the research that has been done, and answers questions. Why it would matter how many posts that takes, is beyond me.
