I have used a stick of hot tinch tools for years and I always loved the way it fits into my hair, but unfortunately, my old iron has no dual voltage. I bought this curling wand as a last-minute purchase to take me with me to Europe (France, Italy, Greece) and I was not disappointed. The item is definitely double voltage and works using only a simple plug adapter (no transformer is not needed). I did not have problems with controls or heat when in Europe. I have been using this not stop for approximately 3 weeks and it is my new favorite curler. The size of the barrel makes really beautiful curls and the oval shape makes the curls look more natural and mix in the natural curls / waves of my hair. I have used it up to 350 and the curls the last two days at least (the second day becomes more wavy than curly, but it still looks good). The curly wand is long, much longer than a typical flat iron, but as other revisions have been mentioned, it is very light and easy to pack (and I packed very lightly for this trip using only a 35L transport backpack). The travel bag is also very useful. For the price, this curling wand is worth it.
