We are talking about another level of comfort that can only be compared to the Gillette Sensitive razor, with the difference that with Wilkinson you will shave much faster because it requires fewer passes.
These cartridges are intended for the Wilkinson Hydro 5 series machines, where in the Avdanced model to which they correspond (although they are compatible with all Hydro 5), a second hinge has been added slightly lower than the first. This does not affect the depth of shaving, but it greatly increases comfort, which I consider to now surpass even the Gillette Fusion Proglide. If I had to have only one razor, I would choose this one.
