I had bought the razor Mach 3 Sensitive few months ago at the drugstore. Before that I had the supposed best shaver "Gillette Fusion ProGlide Power". Although I must say the ProGlide is also very gently and thoroughly, but nevertheless I am sometimes cut while shaving. I have strong growth of beard, which plays an important role. The Mach 3 Sensitive shaved just as thoroughly and is skin-friendly than the ProGlide with me! It may also be that my skin does not tolerate 5 blades, and therefore are 3 sound better. In addition, the blade head by the Mach 3 is smaller than that from ProGlide, making shaving on problem areas (neck, chin) much easier! With the huge blade head from ProGlide one comes to individual hairs on the neck ran difficulties!
Conclusion: The Mach 3 Sensitive is definitely a top razor which is very thorough and gentle on the skin despite my strong beard growth! Moreover, the blades are significantly cheaper than the ProGlide. The durability of the Mach 3 blades are just as good as the the ProGlide, so clear buy recommendation!
