Have the hair half a year ago bought. And now it's broken. The fan is made of plastic and the individual sheets have cracks get, so now is the material for and scrubs in use against the housing (veeeery loud). Have expected eiemn brand product more. Pay me now again a "Billigföhn" set as I had him before, who has held for 10 years. And if I'm honest, I see no difference in my hair to my predecessor without ion.
