Here he had to invent a razor! The bar is really cold éfficace while shaving itself is normal for an electric razor, it must pass several times, and in all directions. . . . The cold prevents the skin from being irritated, flushing, so that it shaves with pleasure, and even aftershave is optional! ! Finally, and as negative, the D / A and Cold buttons are a little big, and I tended to push them over while shaving, but hey, we'll do it. . . . After shaving, I empty the machine of hair, and then I put it in the cleaner, charger, like that, the liquid charging takes longer, and is used to the end! ! ! !
