Hi Emre, and welcome to The Shave Den! I am glad you joined us! Regarding your poll, after trying over 90 different blades, I settled on Gillette Rubie Platinum Plus and Gillette Platinum. These blades last 7 days each for me, and give consistently great shaves. When purchased 100 blades at a time, the cost is about $25.00 including international shipping. Twenty-five dollars for two year's worth of top-quality blades is a fine bargain.
