I am a satisfied user for years of Braun shavers. Currently I use the 7475th
Scherteile I change regularly (1-2 years) and had been always very satisfied with the quality of the shave. Ie with new shear parts, shaving went slightly out of hand, the result was a smooth skin without major skin irritations.
Recently Braun introduced for the 3000, 4000 and 7000 series new shaving unit under the name 30b.
I have now ordered these shear components for the first time and was totally disappointed with the quality of the shave.
Normally after a shearing part exchange was shaving slightly out of hand. The new shear parts, a significantly higher amount of force is necessary, bodies must repeatedly be shaved and the razor makes a noise (very high frequencies) that are unpleasant.
The sound like unimportant, but the quality of the shave is just pathetic.
I complained directly at Brown, where they told me that the old shearing part design will be phased out. Thus, it is time for a new razor, because with these shear parts I can not work every day.
