Packed this for a two week trip through Europe and it saved me a fortune on coffee. Just fill a cup with water, plug it into the 120V outlet, and it's hot in a couple minutes. The dual voltage thing was the whole reason I bought it.

Boiled water for tea in my hotel room in about three minutes, which beat waiting on room service. The dual voltage thing is what sold me since I travel between the US and Europe, and it worked fine on both. Small enough that it barely takes up space in my toiletry bag.

Tossed this in my carry-on and it saved me on a two-week trip — heated water in my hotel room in about five minutes flat. Love that it handles both 120V and the other AC system, so I didn't need a separate converter overseas.
