Its effectiveness lies more in its power of breath in temperature! And that is a big plus because we do not burn the hair leaving it to 1. (ie there are two possible temperatures change) I was very surprise by turning, when all that was on my sink flew in the air by his power. And if you enclanchez more turbo, it's limit bad feeling being whipped back! The results are there, thick semi-long hair I put 10 minutes to dry the turbo mode, convenient for busy mornings! Moreover it is rather quiet, and the wire that connects to the power outlet is very long. We think there is not enough but when the plug is away from the mirror which is handy! It is light in hand, small size and its design is nice, modern! I think its quality is very good value for money!
