I needed a nose trimmer with 2 qualifications: comb style trimmer and rechargeable. I picked this one becauase it has both. My old trimmer only came with the traditional circle rotary trimmer head which does nothing for me, but this one comes with both a comb and a circle head. The cuts were clean, no pulling, no left-over hairs. I give it 3 out of 5 stars though because the unit kept shutting off on me because you have to hold it a certain way for it to operate.
