Actually, I'm with the Braun Series 7 quite satisfied as far as the shaving performance, processing etc.. Actually, for the purchase of this device is only half the story. After 1.5 years, the cutting performance of the shaving head subsides. So stehts indeed in the operating instructions and is so far ok and calculable. Then you need a Replacement head only produced by Brown. This, with 45 not exactly cheap, but of inferior quality so that it already ranges from the cutting performance in quality and duration of insolence or rip-off. Means for me, Brown provides a super power off and once you get to the brand / device delivers you only inferior quality to the customer forcing at even shorter intervals to buy overpriced replacement shaving heads. This is not my subjective opinion, the opinions of special shaving heads at Amazon are full of the same experiences. These reviews we read but only if you have already purchased this product and it is therefore too late. From my perspective, I can not recommend buying a Braun shaver completely. Who now thinks I'm an employee of a competing provider and want to Messrs. Brown do poorly you want but please read my review history. In addition, it seems to work on the same principle in the Fa. Philips. I tend almost to the these two companies have agreed to go around and this was almost a complaint with the antitrust value.
