Small balance after 8 months of use: Unconditional mechanical shaving for over 40 years, the approach of this radical change was not easy and my choice fell exclusively on high-end models of various known brands. I was seduced by the solution of 3 independent heads of the Philips brand, but the inability to change the battery (whose life is announced to 3 years) was the prohibitive barrier, while Panasonic explains you how the battery is replaced! Furthermore critics on the Net for Panasonic were particularly complimentary. The grip is very good, position, balance and ergonomics have obviously been well thought out. The shaving head, however, very massive is not an obstacle to the effectiveness or accuracy. The volume does not bother me; I did not need to mount the volume on the radio! Shaving with foam or gel (found almost mechanical shaving habits!), I was really amazed by the efficiency, including a 3-day beard. Provided to spend a little time and sometimes give one or two shots mower (it is really too small!) In the neck, I do not find any difference with a mechanical shaving using a razor to 5 Gilette type blades. Efficiency is further complemented by a shaving comfort I qualified without hesitation great time. And of course, no more cuts and irritation. The battery is quite satisfactory and ensures daily shaving week (depending on the time we spent there). The central cleaning / charging is efficient, fast, quiet, and really economical with the use of only one to two cartridges per year, depending on frequency of use.
