I have about two weeks of dedicated DE shaves under my belt now and things are looking pretty good. I'm using a Mergress and have not deviated from the minimal setting. Also, I have the beginner sampler pack from WCS and have found a happy spot with the Crystal blades although I haven't tried the Reds yet. I'm pretty comfortable with the way my neck is mapped out but still trying to perfect my lathering technique. Today's shave was not as comfortable with the Crystal and I'd like to know how many shaves I should expect from this blade.
