After a philips rotary heads (inefficient principle I think), a linear grid braun and motor, a Remington grid and obviously in planned obsolescence, I decided to try the Panasonic outsider. Fortunately, it is better than my old equipment (but also later). Shaving is mild and pleasant (only tested dry, not in the shower) and the result is neat, but provided you take the time, often go to the same place, it is the weak point. Small and forth can be more effective than large courses, especially for hair mustache side. The grip is very convenient. The only drawback is the small retractable mower that opens onto the back of the razor that is forced to rotate 180 °, and alternate this movement to move from the use of the grid to that of the mower. Battery life: I have noticed a WEAKENING after 18 days, but I'm not a hair that could embarrass a razor. I therefore intend recharge every 15 days. The basis for charging has a cord over 1.50 m. Attention is unstable because too lightly by the weight of the razor laid vertically, which has its center of gravity rather high.
