It's not my first nose and ear hair trimmer / trimmer. He works as normal with a AA battery that comes with. Unusually for me were the various essays. That I did not know. The Nasenhaartrimmmer still looks normal. But the ear trimmer is new to me. That you should try once at another location. The on / off switch is a rotating mechanism. I find that too cumbersome. With one hand is not feasible. There is also only 1 speed stage. The combs operate at my eyebrow styling. But ... the hard plastic combs could have been softer. A fully functioning Remington hygiene Clipper with small accessories. Not bad, for me mediocrity.
