The brush exfoliates very well making the skin smooth and luminous after using. It does its job perfectly. The brushes comes with various size and softness. I love the body brush and the pumice stone very much. Most of the electric cleaning brushes do not have the body brush option. I do love the feature in this kit. Kit works very well. It requires AA batteries. I use reusable batteries for them. It works perfectly. NO cord so no tension of knots. Travel easy pack. Also the kit comes in an attractive box which makes it a pretty gift incase one prefer to gift it.
