I persuaded (I'm a dad) by some comments and I bought this for my great brush that has medium long hair and always took a long time to do her hair in the morning moaning if we dare wield the brush in its place. She's great, even my wife who was very skeptical could only see the metamorphosis of my daughter during the morning styling sessions. It slides, it's amazing more complaints, frankly bravo. To spoil anything that is French, not really worth it!
