I had my first encounter with the Derby premium. Derbys (the green ones) don't regarded here as good quality as far as I can see, and with any order the "comes with free tuck of blades" means the green Derby... yet to be tested
the premium was fine for me, nothing to write home about, not the sharpest and I felt a very mild, very short irritation after the shave, but there's always a chance my technique casuses this not the blade. I'm OK with the Derby Premium, worked well.
