Review (5/5): Solid versatility for travel
This solidly built, fast-heating combination curling iron and straightener works with both U.S. and European voltage, with the appropriate plug adapter. It does a very good job on my very stubborn hair too, thanks to the adjustable temperature (marked in Celsius) and seems to be very sturdy. Comes with a little velvet drawstring case for travel. I haven't yet had the chance to test it with European voltage, but expect to soon and will update if there are any issues.
I especially like the fact that there is an automatic shutoff for safety, and the tool takes only seconds to come to temperature.
If I have one small quibble, it's that it's a bit thicker and bulkier than either the straightener or curling iron I normally use, which isn't as convenient for packing, but since this is a two-in-one tool, it's definitely worthy of the space it takes.
