Scalp care available Dryer power class: 1200W or more Compatible AC voltage: 100V compatible Foldable: Yes #Aderans #Aderans I received this from someone, but either I'm using it wrong, or it was broken to begin with, (The seller said it wasn't broken.) The following lamps don't light up: - WARM - HOT - BEAUTY When I dried my hair with the scalp attachment, it felt good on my scalp. Lukewarm air comes out, but it's not what I'd call HOT. It's more like, "a little warm." Please understand that the lamps don't light up and hot air doesn't come out before purchasing. Thank you.
