Derby Extras were many wetshavers first blades, myself included. When you don't know what you're doing, you get tons of razor burn and nicks. And despite knowing it's your fault, you write off the blades and bin what you have left. That's what I did years ago, and I'm willing to bet you did that too.
Now that I have plenty of experience, I decided to throw a tuck of these in my order and waited (im)patiently for it to arrive. Although they only last one two-pass head shave, that shave is very comfortable and effortless. I'm currently breaking out from a new cream, and none of the pimples got nicked in the process. Had it been any other blade, I would've been bleeding all over.
I'm not telling you to go buy a full 100 pack of these blades. Not even I will be doing that because of longevity. But I think if you're a couple bucks short of free shipping, you should toss these in and see if you have better luck with them now.
