the F7790 Remington razor shaves better than Braun! very fast engine, which also counts in the shaving quality excellent! farewell Braun (I compare with a Braun Series 5 550 who shaves less!) small inconvenience but me personally is equal, it weighs a little heavy ... attention too, he has not a good mower unlike Braun Serie5. but higher quality shaving at Braun shaver really very good! charging time dépassanr expectations! incredible: the motor runs at 150% even when the load is zero! solid
