Rough sounding blades
I use this product for my head and beard as well. When I tried it for the 1st time it eS very loud and rough sounding  so I put some wd 40 on the blades and it purred like a kitten. Some what disappointed in the fact that when you buy the trimmer it says it never needs oiling. Guess that's not true when you buy the trimmer head separately.
