I have a short haired mixed breed and normal metal combs leave her covered in little skin flakes but this leaves her coat looking really shiny and smooth with no skin irritation! It's good for finishing off my sheltie too.
One thing to mention- it doesn't hold on to the fur like a normal comb/brush so you'll end up with hairs all over the floor. I put an old towel down to catch them or else you'll need the hoover handy!!
