Ball Stretcher for Turkey Neck

I have heard a couple of people mention using a Ball Stretcher when PEing to keep the scrotum skin back therefore not being stretch with gains causing turkey neck to stop forming further. Just curious as to what people think! Anyone had any success with this, and if so anyone know of a good leather ball stretcher? Just trying to experiment.

I bought mine from ebay for 5 bugs but i’m new and still don’t have a turkey neck (trying to prevent it).
