Just used my second blade and just like the first I'm very impressed. Going to try a longevity test just out of curiosity. Finished my third 3 pass shave today and there's no sign of the blade losing its edge or smoothness. Think I will easily get a fourth shave from it and then if it's still going may try pushing it to a fifth. I never push a blade past 3 normally but this thing just seems to keep going. Very quickly becoming my new favourite.
I got six shaves from the first couple I tried before they got binned
