1. This variant of Panasonic and some other party with a round cutter head, which functions according to the system, random unit which hair in one of the cracks is separated, much less effective and
2. The version of Philips (and possibly even others), which have a very small slightly diagonally arranged blade ähnelich at one longhair Scheider. This can conveniently be achieved at any angle in the nose and be "trimmed" without gekitzele and rumgezupfe.
Option 1 I give due to the numerous disadvantages and the poorer outcome 2 stars, version 2 gets 4 stars because this is definitely the more practical and more convenient system.
A truly perfect solution does not exist. The Philips is better suited by far for a bit longer hair and the Panasonic is a bit better then with the "remnants" clearly. To put it hinzukriegen well as possible, I have at the moment both Rasiersyteme in operation only Philips, Panasonic ... then :-)
For the combination solution I would give a total of 4 star, if that were possible.
