The brush is nice and light, sits comfortably in the hand and when I have finished blow-dried my hair after just 10 min., Then the handle is only lukewarm. The ceramic body is, however, quite hot - you should blow any longer, he might even be too hot. The vents are really great, because my hair is really dry faster and thus I save just 2-3 min. Each morning. Not much, but I think it's great ;-) from ion technology I realize, unfortunately, nothing. My hair is just as charged as the previous brush well, even though I often use a flush and always spray Heat Spray on your hair, so my hair should not be too dry and also not feel so. Too bad ... there's a star deduction! Prima, but I find that there is the brush in sooo many sizes. I opted for the 45 / 60mm. This size is really perfect for my step cut. And one more advantage to my old brush: there are no annoying grooves on top of the handle, remain stuck where the hair and it ziiiiept. All in all I would recommend the brush so if one does not wish to ion technology!
Update 2/27/2014:
Unfortunately twinge but - after a long, almost daily use has been found that my hair like to stay "stuck" on the handle or at the transition brush handle or get caught there and doing quite hurt. Have naturally tried to keep the brush differently etc., but it had twinge again. Therefore, there is a star for deduction as a hairbrush should be designed in my opinion, that this does not happen.
