Got the razor and tried the same course. Have not shaved an extra two days and was surprised at the quick shave. I myself have very empflindliche skin and have arge with razor burn problems. Even without switchable cooling shaved the CT4S so quickly and thoroughly that the skin is hardly flushed. The switchable cooling is excellent. I have to mention I have to shave one half of the face without cooling and the other side. I am pleasantly surprised. What I find unfortunate is that the shaver to charge an extra needs in a charging cradle.
