Adapts the Proglide of Gillette for 4 years, I wanted to try this brand for a reason cost. I shave every 2 days. And the big mistake! For sensitive skin, I advise the Proglide (even without the "power"). Upon first use of this Hydro5, the shaving quality is a Proglide which already has 12 days. I even pulled off a mole, something that never had happened to me until now. With blades, after passage, the more we feel a film of shaving foam remains on the skin. So the price difference is largely justified by the quality of shaving. FYI, a 1.50 hydro5 blade shaves me 5 (10 days), whereas the competitor 3.70 me shaves 10-13 (3-4 weeks).
