Slow shaving
I'm not sure what is wrong with these, but it takes me almost three times as long to get a fair shave than the original blades.  I've been able to shave dry for years, but have had to start using a pre-shave lotion to get a halfway decent shave without burning my face.  It could be that I just have a heavy beard.  Hopefully these work better for others.
