Good quality as always!

Does what you'd expect

These blades are great. They're priced reasonably and I get a good 8-10 shaves out of each one before I think about swapping it out. The injector system is also a breeze to use with my single edge razor. I really like Supply Co. and will be back for more gear in future.

Half happy !

It appears that I cut myself easily and bleed.The blades are either too sharp or not properly orientated !?
I also need to correct the hairs that stay near the nose with another razor!

Back to the drawing board!

I an only giving this one star because of the injector design flaw. The blades can become very easily misaligned and when injected that way the razor won't shave properly. This could be corrected by an addition of a plastic insert that you remove and reinsert after the blade is injected. The two pins of the insert would seat through the slots on the razor to keep then in place and aligned. It would also serve as a safety device preventing blades from being removed from the holder.

Love it

Got into wet shaving but really struggled with DE safety razors. Razor burn, bumps on neck. Tried a cheap old injector off eBay. It was way better. So I got one of these bad boys. Incredible. Everything these wet shaving junkies pitched me on came to fruition. Cuts so smooth. Effortless. No irritation. And it looks awesome in the stand. My brothers definitely getting one for Xmas.
