The product corresponds to my expectations: it allows to penetrate deeply care leaving hair soft ... Furthermore, balancing this with suitable curlers, there is a very good compromise to be leveled effortlessly ... small problem: the word "silent" is a bit exaggerated and should be withdrawn by the manufacturers because the noise of the hairdryer is still clearly audible (difficulty to watch TV at the same time as I thought to do ...) but the noise remains bearable!
