Glad it was helpful!

If you hold it so the dome is pressed to your head it’s too hot ( maybe slightly less than Supersonic) if you tilt it so it’s not right against your scalp it’s not too bad. I still had to regularly press the cold shot cuz I found it too hot, but I’m sensitive. I returned it for this reason.

@tressobsessed1 Thanks for the reply. I think you can buy the dome diffuser on its own. Dyson, I believe, has said that the dome diffuser is compatible with the supersonic it just won't have the learning technology . If the dome working with the Nural was significantly cooler, I'd buy the Nural. If I just buy the dome diffuser and I still find it hot with the supersonic, then I won't have wasted so much money, lol.
