After googling and read customer reviews eternal I came on this hairdryer.
I am thrilled the hair after blow-super soft, it is hardly what from. I gave the hair dryer also my grandma's 80th birthday and she is also thrilled because the hair is so easy to handle. Just set the desired temperature only (I take the recommended optimal setting that I have to never change) and then ask just to level I or II.
The only drawback (and that's why the star deduction): My hair after blow-dry often vertuckt, I must be very carefully comb the hair to unravel again.
