A 5 blade system it should be already, so I'm laden at Gilette Fusion. The Proglide or Proglide Power was me then but extremely overpriced.
The shaving is a little more thoroughly and is gentle on the hands than the Mach3. The differences are minimal and fall to only the direct comparison of the two razor.
The extra blade on the back is really handy and can be used in many ways.
Durability: The razor blade lasts as long as the at Mach 3, with me so in about 3-4 weeks exactly. But they will not clog so quickly when facial hair although they are arranged more densely.
Quality: It can happen that some blades are processed not focus properly and not clean. They are therefore mostly useless for my sensitive skin, which is simply an insult for the price of blades.
And since we are already in the thick gripe this shaving system arrived.
The price of 2.75 for no less than a blade is still grossly exaggerated. At this price I expect but a 1A quality of the blades and a much better performance than shaving my Mach3. However, this is unfortunately not the case.
I will, willy-nilly have to fish my old razor out of the garbage again, since the price / performance ratio is reasonably.
But who does not shrink from the price for which these blades are a great enrichment.
