Works Well and is Well-Constructed
I owned a Panasonic ER-GN30 nose hair trimmer for several years, dropped it recently and it stopped working so I replaced it with this.  I immediately noticed the superior construction, despite the lower price, of this model.  It feels heavier and more substantial.  The big problem with my prior Panasonic was that the double-A battery's positive terminal (the metal nub), faced downward, it often shook loose, and the power would cut off.  With this model, the positive terminal properly faces upward/north and the screw-in base provides constant pressure on the battery so the power doesn't cut off.  Long way of saying: this model has superior construction.  I recommend this nose hair trimmer.  It works well, cuts my nose hair quite close without snagging and I imagine it would work equally well for anyone needing ear hair trimming too.  I'm pleased with my purchase.
