I want to say that given the nature of my hair curly, I only use one accessory / nozzle, which is the pin diffuser. Having never made a single brushing of my life, I can not comment on the different nozzles (4 and more) that accompanies the hairdryer. That said, I am very satisfied with this machine, which is indeed very good job. It is quite light, color aubergine is nice and the wire is long enough to not remain stuck to the wall. There are three possible temperatures and two speeds (I regret a little bit slower than is already fast enough for curly hair that's not necessarily great), it's classic. The pin tip works well on my hair (which I wrapped for about twenty minutes in a micro fiber towel before), the air is distributed throughout and can form real pretty curls without frizz or mane lion.
Honestly, I'm not transcended but he did what I asked. I guess with straight hair and / or brushes, the possibilities are greater and it certainly takes on even more importance.
