Very skeptical at the outset, I left my daughter alone with this strange hair brush. She immediately adored and said: "It's great, I have no node and without getting mail". God knows nodes, screaming and crying were the ordeal each morning. Over 15mn on a hair late, curly and a little frizzy every morning we spent 2 / 3m ,. A record !!! And more happy !!! So the BRUSH was ADOPTED. We will see the use duration.
