Used with a Senso Touch 3D, this small spray brings a note of freshness to the slides that unfortunately does not offer the cleaning lotion Jet Clean washing tank too neutral. It is difficult to say that the heads work better, but actually it lubricates and it is probably the main advantage of the product (and the heads can rotate better but it must feel to an already quite worn razor). Then is it really necessary? if you have a washing tank, except to give a pleasant smell in addition, probably not, because the Jet Clean washes and lubricates already. But if you wash the heads only on tap, it's a good addition to cleaning.
