Now I was able to test the very simple blade "Mach 3". For me it is subjectively no new inventions, rather a well-known model in another look. Depending on the purpose of this shaving blades to use of course for women and also for men alike. I have the right grip with vibration function at home, but the blades are well suited.
A small Lubra-Gleitgelstreifen exists on this blade. This is in connection with pure water a more pleasant first quick shave allow (if times no shaving cream is readily accessible). This works reasonably well for a short time. I still always use some shaving gel, which is essential for the even smoother shaving.
Conclusion:
The shaving is pleasant and thorough in this blade model in conjunction with shaving. Large differences from other models I feel not. One can therefore recommend the blade. The replacement rate is still fairly reasonable. In my experience, I get about 5 months with a 5 blade set, but I shave every day not me.
