I got the Gillette Flexball razor technology after a few years of having a previous Gillette razor, and the benefits that the flexball provides were noticeable instantly. The design concept is rather intuitive: a ball can roll over uneven surfaces better than a flat device can. Since getting this razor, shaving is an absolute breeze, taking way less time with way fewer cuts. With this simple little design invention, Gillette made their razors a sleek piece of technology.
