Cut with the performance of the nose hair, I am completely satisfied. Only the quality of the art is magelhaft. First purchase in April 2013. Exchange of the device in October 2013 because the device simply no longer ran despite new battery. Now we have the beginning of May 2014 and the new device the same again. Here I use the hair trimmer than once every 14 days. The device seems to be designed for 6 months. How Amazon wants to make in the long run with the warranty is beyond me :-)
