My old Trimmer has cost only 39, comparatively the PANASONIC is almost twice as expensive. But it is also clearly the better device. Housing design and handling are clearly better. The PANASONIC comes with 2 ridges, open the adjustment width of 0.5 to 20mm. These lengths do not allow haircut per se and are designed for Bartbehaarung. If you want to cut the hair of the head, you have to make do with a styling comb. What I like good, is the command dial for the combs. It's all around tangible and solid graded, so there is no set-up errors. You look at it between thumb and forefinger. In addition, the ridges stuck on the snap mount, and not even be moved. The experience with inexpensive equipment shows that grid fastening be softened with time, and walk the ridges on the move. That seems to me to be prevented by the slide principle. Unique Plus! The PANASONIC comes partially charged, it may be necessary if used immediately. Attached are precision mechanic oil, cleaning brush and a sleek protective case, but only fit into the device itself. The manual is thick, and designed for 16 languages. In my opinion, dispensable because Internet. In addition, the handle by itself understood. The AC adapter has an irreversible plug, the correct polarity when charging is ensured. The trimmer for a close trim can be ejected as with razors. It is only suitable for for rough, about the preparation of a wet shave. The shearing work itself can be used on bare skin poorly, because the blade ends are quite pointed. That would be about the only negative I could find. Because of the processing that promises longevity, and the thoughtful design: full 5 stars!
