Thanks, All. Now, I just have to carry one hair straightener.
Just a word to the wise, I had appliances that I bought in Europe and even though I bought a voltage converter so I could use in the US, the fluctuations in voltage burned out the appliances. I also blew out some of my US appliances in Europe when I used with converters. I now have a European hair tools and US hair tools. They also work more efficiently.
The dual voltage appliances work well, but I stay away from converters now.
