This is the perfect mens or womens hair trimmer for the professional or for at home user. It is engineered with a powerful rotary motor that runs at 7000 strokes per minute yet emits low noise and vibration for a steady cut. The trimmer can slash through coarse hair and is gentle enough for beards women and kids. Since it is corded the run time is endless for the barber shop being able to go from one client to the next without having to recharge.
