A:AnswerHi there Uri, this is Tia from Dyson. Within the first few uses it is normal to expect a smell from any brand new appliance with a heater element (e.g. toaster/oven/kettle etc.). The smell will fade with time and usage.
If there is still concern with your Dyson unit, please don't hesitate to reach our support team at [email protected]. Thank you for choosing Dyson technology!
Best wishes,
Tia

A:AnswerNo, they are not interchangeable. Although, there are youtube hacks using a universal diffuser on the top part of the machine and have been able to successfully diffuse their hair with the airwrap. You can get this machine and do this if you use a diffuser for your curly hair and can not get immediately a dryer with a diffuser.
