Gotta give em at least two IME. Until I experienced it for myself I was a little skeptical when I heard of blades getting better, then I bought some med preps and found out for myself that yeah, you gotta give em a chance cause some actually do improve
Three isn't too bad. I've even chucked blades that went belly-up after only a few shaves. (Believe it or not! )
But, it's the guys who toss out a perfectly good blade after only one use that leave me utterly perplexed!
