I found this:
"....Anyway, overall, the product is really a fine example of craftsmanship. I've not even plugged them into a sound system yet, as I have them firmly wrapped around my testicles at the moment in an effort to keep my own sperm from impregnating my brain and taking over my mind. So far, so good - I can't speak enough about the reliability of these cables."
Just one review below I found this:
"i love beating my white slaves, or even passerby's with this product. its has a more mellow and more tonal and hence superior sound as the skin eviscerates with a goodly floqgging using these video cables whats not to like?"
I suspect some reviewers might be using them improperly.
