The search is over. Kudos.
I'm a hairy guy. I mean REALLY hairy.  My chest hair grows back in a few days.  Most of my body hair is fine, but hair on the balls...? No way, not feeling it.  I've tried for years to fine some method of removing the hair that's safe and effective, but its honestly been a fruitless journey.  One day Manscaped came out with their Lawn Mover 2.0, a razor literally designed for shaving balls.  I thought I had finally found the one. But just like every razor I'd tried before, it cut my balls like a cheese grater.  After I got a centimeter-long cut on my balls and bled for hours, I decided I was not going back to a razor.  I'd either find another way or they'd stay hairy.  In a moment of desperation I googled "nair for balls" cause I know normal nair isn't safe for the balls.  This product came up.  Reviews were mixed but I was desperate and went for it anyway.  I followed the instructions exactly, and the moment I stepped into the shower, I watched in disbelief as my balls transformed from a messy jungle to a nice smooth surface.  I'm honestly surprised how well this worked so I had to come and write this review.  From what other people are saying, it may not work for everyone, but is sure as hell did for me. So I'd say if you're as desperate for a solution as I was, at least give it a try.
