Now the change after 30 months use, however, was more than overdue, the old shaving head has left a lot of red skin and small stubble. That's no longer the case with the new shaving head. The shaving is again gently and thoroughly, to me there is even a touch more thoroughly than with the supplied shaving head before. The blades are really sharp again.
My Advice:
Not shy away from the quite high and useless translucent investment and calmly something "treat" and appoint the new shaving head.
The change is very easy - just pull the shaving head and attach the new head, it does not even matter which way round to attach the shaving head. The shaving is again gently and thoroughly.
Anyway, I'll create myself a calendar entry in 24 months at the latest and then order a new shaving head - it is definitely worth.
