Overall, the Philips Air Styler has produced a reasonable, but not convincing impression with my girlfriend. For her long, thin hair of Air Styler has not enough power - drying takes a long time and thus it takes too long until the hair looks styled reasonable.
The Air Styler works, but is not efficient, so they preferred the combination of hair dryer and flat iron still. For shorter, possibly even slightly naturally curly hair, who would likely perform better Airstyler - for the head of my friend, he was not perfect.
