For years I shaved myself with the Wilkinson Quattro Titanium. I had to change blade once every 3 shaves and when I shaved my head was costing me ca live a blade. I received a gift of birth in the hospital a box "My Papa" which included a Hydro razor blade with 1 January. So I naturally tested and I got harpooned! lol I immediately ordered a subscription of 8 Hydro blade every 2 months. I was planning to use a blade week and the surprise is that I keep the same blade two weeks. So overall it's very good and very economical blade in the end. The glide is perfect and I have no more button since I used. That happiness, I do not change it
