They work but.. [SEP] I can not put my finger on what is going on. Any other razors and foil I have used with this razor have worked fine. These sound like they are hitting the foil and rubbing on it. I added a few drops of mineral oil to see if that would help, it did not. They do cut my whiskers but not as close as they should. Not worth sending back, I'll just buy from a different company the next time I need replacement.<br />I guess buy at your own risk
