Gillette is the big boy on campus when it comes to making razors and other shaving products and this rotating razor is the newest innovation it has come out with to make shaving easier and more comfortable for men. The Gillette Fusion ProGlide FlexBall razor has a rotating ball between the handle and blades to allow for rotations around the contours off the face.
When companies come out with new razors, they typically add more blades to make cutting down the hairs easier. This isn't the only thing that needs to be done when it comes to making shaving easier though. Every man's face is different so having a razor that can adjust itself to each man's face is a definite bonus.
