Powerful patented technology is not comparable to ordinary razors.
Philips, the Dutch brand: the first double-headed and triple-headed rotary shaver in China, with original self-grinding double-layer cutter head and cutter net in fine steel, the Netherlands.
Needless to say, a century-old world-class brand.
The blade principles of the two brands are completely different. Braun is reciprocating and Philips is rotating. The specific difference was seen on a blog named Li before.
There is also a direct comparison, not only what beard type is suitable for all cutter heads, but also the model.
