Review on Bolzano Superinox Inossidabile Double Blades by Shannon Saunders

I tried these blades on a trial and fell in love. I ordered a pack of 20 and have used 2 so far and they have been terrible. I'm not sure if the blades they offer in the sample set are of a higher quality to convince buyers, but I'm really disappointed. On the first pass, I felt the blade pierce my skin. Halfway down I felt a razor burn form and blood ran down my face. The attached photos show shaving marks from shaving with the second blade. There were no problems with the blades in the sample set, but the blades in the 20 piece set are terrible.
