The Remington F7790 is very powerful, even with a heavy beard. But he is also very noisy and more delicate skin he reaches quite through, so sometimes skin irritation (riding tongues) can occur. The trimmer is a little too small and not well used. He does not get far enough behind the Scheer head out. My predecessor of Remington double Scheer head and larger trimmer gefiehl me better. But the F7790 it does. I think that the triple Scheer head is a bit exaggerated. Twice is enough. The charging station is a good thing. The thing is now no longer so rum. I think, however, that they should not constantly hold the power. The F7790 comes with daily shave two weeks without electricity from.
