Blade not sharp - dull after a short time

Have bought the blades because they have the best price / performance ratio on Amazon. Unfortunately, I am disappointed by the quality EXTREME!
Had been several Gilette Mach3, also Nassrasierer other companies and now the Gilette Fusion Power Proglide. So not a newcomer what wet shaves terms.

However, these blades are by far the worst that I have ever bought!
From the beginning, not really sharp. Already the first train with a whole new blade was almost painful. After 2-3 shaves the blade's time consuming that I no longer wanted to use.

Have in principle more sensitive skin, but that was for me a first! Even very consumed my Mach3 blades (I use currently playing, as these blades are useless!) Feel better than this after shave 2-3 times!

Very disappointing, way too expensive!
