Is this product dual voltage?

No but I use a step up converter (something like this http://www.amazon.com/Goldsource-STU-750-Voltage-Transformer-Converter/dp/B0022TL1BE). Using for 20-30 min here and there with a converter should be ok but prolonged use on a different voltage over time (or using it for multiple hours at once) might decrease its lifespan. Have had mine for ~1yr.

Yes, mine is dual voltage. Therefore, it works fine using an adapter without any weird temperature changes or "humming" sounds. Mine has an American 110 plug but I have used it with the appropriate adapters in Germany, France, England, Ireland, Italy, Austria, Belgium and Czech all without problems!

the unit runs off a power adapter that's plugged into wall outlet so there's a chance that that adapter will be dual voltage but I dont know. I returned the unit and dont have with me.

Yes. The instructions say "Dual voltage for worldwide use." The specifications say "Rated Voltage: 110-240VAC". It does not have a switch to change from one voltage to the other.

I really don't know, don't have the box anymore, however, most hair care products today are dual voltage. Sorry I can't give you a definite yes or no.

No, it is not dual voltage. But this product can be used if you either purchase or borrow a converter from the hotel you're staying at.

Its 110-240v input. I received mine today and it is dual voltage for both the units.

No its not dual voltage when I was in the 220-240V I used my power converter box at events.

I do not believe that it is dual voltage. I believe you could use an adapter for international travel just like you would need to use for your computer and razor.

I just searched mine again for any indication of dual voltage. Mine is 110/120V only.

Don't think so. I live in the US and use 120. I checked but didn't see any stickers indicating it was a dual voltage light. Sorry, it's a nice light.

Yes... It is dual voltage. There is a little sliding switch on one side that moves to either "125" or "250".

I don't believe it comes in dual-voltage. Mine is 110V/60hz. I use it in Europe on 220V/50hz power through a 300W step-down transformer (resulting in 110V/50hz). Been using it like this for nearly 3 years, no problems. It occasionally makes a crackling noise while changing the volume setting, but otherwise works perfectly. Hope that helps.

The description definitely does NOT say dual voltage and it would likely specify if it were, and the other iron I have that is virtually the same is not dual voltage--so I would not risk it unless you hear from the seller directly.

No, sorry, it isn't dual voltage. You would definitely need to use a voltage converter with it for 220v.

According to the box, it is 120V (see customer pictures). I have not tried it outside the US to see if it is actually dual voltage.

No it's not a dual voltage. You would have to step it down to 110 with a converter.
