I have used this blade for over 10 days at three times shave. I have these blades attached to a quite elderly Venus handpiece, which succeeded without problems. I am very pleasantly surprised by this blade. In the meantime, I resorted to a 3 blade Nonamefirma. A comparison is actually just barely possible because these blade Venus play in another league. The shaving is thoroughly already on your first stroke. I particularly like the sachet, which straighten the hair and skin gently massaged. By pillows, a certain safe distance from the skin comes into being. Thus, I have also been injured in any shaving.
