The really unbeatable price and the good reviews have led me to a test. The order was delivered quickly. But that was it for now I can say on the positive to this shaving system. I find shaving with this blade rather unpleasant. The cutting area was partially only one centimeter width in the central region of the blade and felt more after scratching as to slide on. I think that the blades are too hard / rigid and able to adapt so even slight curves of the face / head. The shaving was so unpleasant that I can do about longevity of the blades no statement because I have shaved only once with each blade and after the 3rd shave everything already got rid of.
