I use them everyday. I can get 7 shaves out of them, although the last shave are too are stretching a bit...different strokes/different folks...
I think they're great based on my experiences so far. Kinda tells me all these razor blade discussions are about the most pointless ones on shaving forums. Some people think X blades are garbage and get one lousy shave with them. The next guy comes along and says X blades are terrific and gets five good shaves with one. The only useful advice is to try whatever blades you want and pay no attention to what any of the rest of us say because it's *your* face.
So far, between the Derbys I started with recently and these, I see little reason to bother with anything else. I'd rate these and the Derbys as excellent with good longevity for a medium light beard like mine.
Does it matter? They work for you or they don't. It's under $2 for 10. Try them and decide for yourself.
If you expect to relate to the matter discussed on this forum to expert answers, you're at a wrong place....I have yet to read one actual expert answer on this site that isn't based on opinion only...
...My point is that talking about razor blades is even less useful than talking about the weather. A blade works for an individual or it doesn't and it doesn't matter a whit if it's made in Bulgaria out of recycled Yugos or the finest Japanese surgical steel that cuts most inexperienced users who don't open the package correctly, much less shave with it...
