For over 20 years I shave with Brown. In December I decided on the Series 5 560. Since then I have used it about 15 times and has to write: It's a disaster. He shaved neither thoroughly to the unproblematic places still problem areas (neck, chin). In addition, the skin becomes extremely irritated. The total shave lasts much longer than with all previous devices that I've ever owned. Various test reports give rise to the suspicion that it is a design flaw. Conclusion: better buy blades and shaving wet.
