I've only used it 3 times so far but I LOVE that it's so lightweight and quiet. it sounds like the bmw of hairdryers. it has three heat settings and two blower settings, which is very nice too. I have long hair that I dry with a round brush and I usually use the hottest setting and the highest blower but today it seemed to be getting extra hot so I bumped it down to the middle heat setting. hopefully it won't overheat or damage my hair. (my last X5 melted its own concentrator nozzle!) I also like that it came with 2 concentrator attachments and that they are really narrow (the last one I had was more open). so - aside from worrying a little about the hotness - I really love it!
