Very good blade, not as sharp as the Feather blades, but very accurate and smooth. If you don't need the sharpest blades that's a good choice. For me I've tried several blades. It's the same category like Perma Sharp or Treet Carbon but not hat level like Feather's first shave.

To me, these blades are like a like a Feather blade on the second shave. They are sharp and smooth. Not sure how many shaves can be had from them since I'm a one and done sort of shaver. These blades are definitely worth a try if you're looking for a blade that is sharp and smooth.

I hate them!!! Felt dull and pull whiskers bad. Irritation around my neck…

I have tried these blades in 3 different razors now, and I honestly don’t see what all the fuss is about. I would call the shave very harsh, or rough. I used 3 of the 5 blades, and it was very uncomfortable every time I used them. Not for me.
