I was using previously MACH3 blades whose cutting comfort has declined in recent months, but not their price. I am pleased with these blades, which are not given, it must be confessed. But the difference in comfort is very clear. I tried distributors blades but in was not happy.
The fifth blade is a plus.
But one of the highlights and can be misunderstood, it is the "plastic scraper" that removes excess foam. Much comfort must reside there.
