Not recommended on thick facial hair; a solid introductory blade
Very good shave, but patchy; irritation is common
Got a great shave testing these blades. Had good longevity and it's a very smooth and comfortable shave.
Not bad, but...
Got a pack of these out of sheer curiosity: my past experience with Derbys has been mixed: I think they're really designed firmly with the "single-pass" shaver in mind, as the first pass is terrific, but subsequent passes are seriously hit-or-miss, and the Premium seems no different to me. If your regimen is "one and done", these might be worth a try, but they're not for me.
While these blades do not give me quite as close a shave as with Kai blades, they are probably the smoothest I have used and definitely shave close enough! An excellent compromise and I will likely continue to use them.

I ordered these in a 5 pack. Upon using these razors in my merker 34, i've compared these premiums to the astra blades, and as much as i love how the astra is smooth and efficient; these are just as smooth and leave less nicks. long lasting and will be ordering more!
