After my previous razors, several Braun, Remington and more Carrera I can say that this razor is the most thorough and thereby hautschonendste razor I've ever had. Even with several days beard he shaved quickly and thoroughly. Pro shave the battery needs 20% of its capacity, that's ok. Through the battery indicator, you can recharge time, which I find very helpful. As the battery behaves in the long term, of course, I can not say yet. From me, therefore, a "Highly Recommended" I would buy again. Addendum after 10 months: If the battery shows 40% reaches it possibly still a shave. But we must not in between fluorrescent then the display goes to 0%, and you have to recharge. As long as you walk around with half-shaved face then ...... totally unacceptable.
