"No Crow" Rooster Collar-any comments welcome

[capebird]

Hi,

I've got a rooster (unintended) who is starting to crow a great deal. Anyone have any experience with
the No Crow Rooster Collar. If you could share your experiences with the product I'd appreciate it.
Thanks!!

I tried two different sized collars on my silkies and they did not work. Good idea but would not waste your money.
