I bought 100 Voskhods off ebay seller unuta77. I have had these blades from different vendors in the past and loved them but these are rough on the first shave and completely unusable for a second.
Wouldn't discount the Voskhods but would advise staying away from this seller.
I find it somewhat frustrating that blades from eBay seem be such a crapshoot. I've used the same seller a few times and they have excellent feedback. I found the same as you with my first Voskhod blade though. So I'm still none the wiser as to if it was a duff blade or that my face just doesn't like Voskhods. To make matters worse I used a Rapira Swedish Supersteel next and got similar results, as I understand them both to be mild blades. I won't do that again, use one unknown blade after another, without returning to a known fave inbetween. I don't plan on testing any more now really anyway as I've found a few that like my face.
