Phillips Oneblade.
No shit, it's an amazing razor for the pubes. Obviously doesn't cut down to 0 like a wet shave, but it's so much easier and comes really close. And I get ingrown hairs easily if I wet shave down there so it's perfect for me.
It's fast, it's reliably, easy and painless. 100% recommend for ball shaving action!
I was buying a toslink cable recently and I shit you not, there was a gold plated optical cable...
