I struggled with this product (model#BC173) the first few times. Once I got the hang of it I fell in love. I have problems with my arms and this product saved me time and energy. I no longer have to use a round brush and blow dryer. This product is lightweight and very versatile. I have even "curled" my hair but simply rolling the tool in an upward motion. Just be careful when unrolling as I have pulled out a good bit of hair. I love the way you can get right at the roots. I have had problems with static but a little bit of hair serum seems to do the trick. I am purchasing one for a friend who saw mine and saw what it has done for me.
