Palm perfect !
Love this handheld electric shaver! The noise level is very low , about the same as a pair of small trimmers. It is very easy to take apart and clean . The Palm Perfect fits perfectly in my hand , which makes shaving effortless. Great value for your money. I really wish it would give me a closer shave, although the quality of this product is still great!
