Mine is ionic and from Walmart. Ionic with ceramic on the end actually. I heard those dry faster. I can't tell the diff in the ceramic but the ionice is nice. I don't get split ends anymore from the dryer.
I think my last one was 20 bucks and this one was 60, and that's a splurge not what I would normally pay. They came with the bowl diffuser and have three heat and two blower settings.
Conair infiniti happens to be the name of this one I have.
