Much better than the traditional tidying methods because of the extra added protection. While there is still a chance to pinch in those hard to flatten surfaces, it definitely provides piece of mind. And I have found that colder is better when the boys are pulled up to keep warm. Taut skin from colder conditions is better than a loose sac that is trying to cool down from the heat!
Speaking of heat, my only knock is that the metal head with the blade gets warmer the longer you run the razor. Can get a little too warm, especially if you're using on a partner and can't tell how warm/hot it is for them.
I purchased 5 extra blades so I had one for my wife's nethers, one for the boys, one for my face and a few spares. Recommend for the ease and added piece of mind.
