The Tzumi Ion Mug is perfect except for one thing, the cup is too small but that's because I'm used to a bigger cup. Probably about 2 times as big, but that's just a preference. It came well packaged, it's like a box within a box. Didn't take any time to heat up to the temperature and I like mine on the lowerest temperature (135) but it has 3 settings, 135, 140, and 145.
