Bought this item in March 2010 to trim my hairline after cutting my hair.Used this item six times a year for a total of 12 times.In June 2012, I turned it on and there is only a hum. The trimmer does not function. Completely dead.This trimmer gave me a warning a few months back. When I turned it on there was only a hum. But after turning it on several times it worked again.This time though, it is COMPLETELY DEAD. So it costs $50.00 for 12 uses, i.e. $4.16 per haircut.
