Hello, of course shaved the Hydro 3 not bad but I go back to the Quattro. In any case, the Hydro for my face is more pleasant than the Gillette Fusion (uses a sword and gone with it, the blades are working aggressively to the face and are final too expensive). But the hydro tends to be large blade. While I care the merger to "board-like" on the face of Hydro is to me "block-like". I can quite explain the highly subjective effect but not, but the size and the angle of the blade head exactly the same compared to the Quattro. Despite "only" 3 blade the result is surprisingly clean, but must in my dent in the jaw more than twice about it. Note: I shave only with the bottom line. For me, rather negative because positive is the lubricant used, overkill, so my judgment, initially "lubricates" he quite violently on the skin. The blade does not last longer than normal, at the Titanium Blades from Quattro comes not have a blade in the shelf life ran. Bottom line, both blades are too big / bulky (merger / Hydro 3) - and I stay at Quattro. Greeting, Rounder6
