The price advantage could not be used

Since I already since years shave the Gilette Mach3 blade, but the price find very high, I pay attention to the repeatedly occurring special prizes at various drug stores. Meanwhile, I have found that there is a special price when the blade the piece cost about 1.50.
So far, the blades were then always as expected, I use a blade with daily shaving about 7 days, then they can be felt dull and it's more of a scratch than a cut!

Now I had bought for the first time this special offer from Amazon.
...... And I was completely disappointed.
I have more than half of the blade used, but definitely needs to remember with any of this pack, that these blades appear dull after 1-2 shaves. Again and again, I once used a blade from the normal purchase at a drugstore and repeatedly felt this extreme difference.
I would advise against any of this purchase. Chill it These are blades 2nd or 3rd choice more!
I myself must confess that I have the blades out of laziness and probably difficult proof not be returned. That's just my dues. Pay only buy me in the future blades where I bought it so far also.
