Charging times: As indicated. This very short. Operating time: As indicated. This well: For both 4 points.
Quality of hair: Very good. Highest among my 5 comparable dry shavers in the last 15 years; even nearly as good as a shave with a blade. And that in older skin, and compared with similar shavers in price range 50-180 EUR: 5 points.
Sliding trimmer for long hair: Too long the apparatus projecting while "shaky". Trimming result only moderately. Hair removal between scalp and upper ear angle difficult and inefficient. Grates on the skin also painful. One annoyance. Therefore, only 1 point.
"Intercept Trimmer" between the two shaving foils: Warning !!! Even if you put on the apparatus at shaving between nose and upper lip according to instructions correctly "at right angles to the skin," one of these trimmers can tear the lip bloody and rasp on a broad area. After the initial injury at the beginning it happened to me, despite caution in 6 months nor more than once. Even on the lower lip when the shaving head slipped in haste on the lip edge. For such a dangerous Macke only shake their heads still 1 point.
Overall: Despite the two dubious trimmer, but due to the unusually good, smooth shave at least 3 points.
