've Tried both
1) rotary trimmer as well
2.) a trimmer, which looks like a small hair clipper (the Scherflaeche is in this only 5 mm wide).
With either of these two could reasonably remove nose hair, 2nd) but was just a disaster.
With the Philips NT9130 I could erstsmals to remove this pesky nose hairs.
The fact that the hair "unfortunately" grow and this pretty itches and tickles, but he can not help.
It really is a vile nature, that with declining Kopfbehaaren to sprout suddenly start in the strangest places hair, where they are completely undesirable.
Two critical remarks:
1.) In the device there is no tactile guide, so you can not feel you should hold the device so that the shaving head has the right position with his hands. So you have to look very carefully in the mirror, so that you hold the shaving head properly. This is somewhat impractical. For this, I give half a point deduction.
2.) The batteries are housed in the lower part and this lower part is both on / off switch. At the beginning it happened to me that I had opened the battery compartment instead of how really wanted, turn the unit on. This is a constructive negligence. To this end, also half a point deduction.
Addendum:
In rubberized black upper part of the trimmer a pattern is embossed, which is on the opposite side of the cutting head itself. This is quite normal, which is why I have not noticed this embossed long. This can be used as a haptic guidance and therefore knows blind where the cutting head is located.
