After reading the reviews, I thought this product could replace my Wahl professional clippers. I was wrong, the teeth on the clippers constantly pull the hair and cause pain. I am returning this thing to amazon. If you have thick hair on your chest and legs and are used to trimming with professional clippers, this item is not for you. You have to go very slowly, what took minutes with the Wahl clippers took half an hour with the bodygroom.
