I tried them to see how they compare to the ones I usually use. Good blades but I prefer the Feather

They arrived with the Rockwell 6S razor. From my testing, they were just OK overall. It was the first time I cut myself while shaving with a safety razor.

They are not very sharp, and for me, with thick and coarse hair on my face, they didn't do as good a job as the Feather or Bic, and sometimes they pull the hair instead of cutting it. I imagine others, as they write in the reviews, find them very good if you have fine and/or soft hair.

However, for the body and sensitive areas, they are a very good choice without irritation. I imagine they would also be good for shaving the head, although I haven't tried that.

Very good blades! I have been using them for over a year and I am satisfied. Each blade gives me 3 shaves (from 3 passes each) and does not cause irritation unlike the feather ones which are sharper and irritate my face. My beard is moderately hard. They don't rust even when I leave them wet on the machine, nothing at all! From me, it's a YES!!

In a search I did on the internet, the sharpness of Rockwell razors was compared to that of Wilkinson, something that in practice (at least for my beard) is not true.

If, for example, in terms of sharpness, Wilkinson razors are 8/10, with Feather being at 10/10, Rockwell razors are between 6-7/10.

As for irritations, they don't cause me any despite having sensitive skin, while their durability (for my tough beard) is 2-3 shaves. I'm good after 2 shaves and on the 3rd shave, it's so-so, meaning I could have changed the blade after the 2nd shave and not gone for a 3rd shave with the same blade.

I'm not saying that the blades are bad, they're just not for me.
