Will the Airwrap Volume and Shape be available again before Christmas?

What material are the attachments made of? i.e.: where the hair gets to. e.g. is the round brush made of plastic or metal? it's hard to tell and it's not written anywhere. Thanks

Is there a possibility to test this new device in my salon? I already have the Dyson hair dryer but it's a lot of money.

when will the airwrap be available? perfect christmas present :)
