I haven't broken them.open yet but can say that the ordering process was smooth.
Just OK, not bad not the best
Saw some good reviews, I think the only people that like these are the people that cant afford or are too cheap to spring for the Feather blades, which I think are much better, stiffer and cut through better.
Best blade with Karve Christopher Bradley.
Feathers were my blade of choice with my Meekur 34C. They are too aggressive in my Karve Christopher Bradley. Wilkenson Sword, Gillette Platinum, Astra, and Gillette Silver Blue competed in a couple-week shave-off. Silver Blues won out: sufficiently aggressive and smooth. That's my experience. Given all of the variables, yours could be different.
Gillette Silver Blue
What more could you ask for? It is a sharp, close, clean cutting blade with no irritation. It is my favorite blade and highly recommend it to you.
Great Beginners Blade
Excellent shave, no irritation or pulling, usually very smooth 4.3 Stars
