When I used the product for the first time I had to immediately think of the many negative reviews. Because really did hardly anything in my hair. No matter how high I set the temperature. Two days later I was then ventured again. It was a little better. Slight Curl were seen and when I was done with the lower section of hair and I turned to the rest of your hair, I was surprised. The curls were now exactly as I wanted them. Great and really wavy. Seems to me that the unit would need a bit of his time in order to carry out its functions properly. The third time it went the way directly as I wanted to.
