I have the equipment for a while now and can make a long-term experience: nose hair trimmer is not working. As others have written only stinks, but he sensed no hair. The shaving attachment detected no stubble, only single longer hair. Trimmer was not tried because I tailor let the hair at the hairdresser and required the device only for the beard. Short battery runtime (you can also use the device on the cable). But now, after a few years, has the plastic housing on several cracks and no longer holding the tradition. When trying to stick crumbled some parts so much that I just can not dispose of the machine now. PS device is Made in China Conclusion: too high a price for the limited application possibilities and short shelf life
