From Preisleistungsverhältnins of Severin Haircare HS 0781 nose / ear hair trimmer set, stainless steel black is very good. The unit is operated via a normal battery and battery therefore not have to if one unit every day so it was renewed almost every 2 weeks with me. The main shortcoming is that that device is defective gegange already after half a year even though I have it cleaned regularly which was very good, the engine of the hair trimmer no longer Drecht itself.
Conclusion: From the price a super device although only for a short duration.
