So in haste and newbieness (and before I found this forum) I placed an order from The Large River website (I now deal with WCS) for 100 Derby blades. Well I finally tried them after a few other brands and they work great on my face. I was worried that I would have 99 blades that I couldn't use. Derby's seemed to be 50/50 around the site as good or bad, but in my case they are on the good side.
