Ball Stretchers

Was just flicking through a load of toys and came across this Ball Stretcher:

What? Has anyone tried it? I would have thought it would have been painful or uncomfortable at best?

Any other thoughts on it?

I forgot to check if it was under BDSM, the product description just said it was to elongate the skin over time making your balls hang lower and have more bounce.

People want them to hang lower?
Good god mine were getting bruised last time we tried doggy.
