Received these blade as part of a sample pack. One of the most uncomfortable shaves of my life. I had two days worth of beard and every pass of blade was very rough, the tug/pull on the beard was quite strong, the blade missed a lot of hair/beard and left me with considerably irritated skin. My previous shave was with a Gillette Nacet blade being used for the fourth time and it still performed like a champ. I will not give these blades a second chance.
