Would buy again
Color: White
Makes great thick foam. Will overflow if you fill to the max line— not so fun to clean up. Best results are 1/2 to 3/4 of max line. Tried heavy cream, whole milk, and evaporated milk. All three work great.

Broken after 6 weeks of use
Color: White
Bought this so I didn’t have to heat my milk before frothing. No longer heated after 6 weeks. Too late to return. I consider this a bad buy. Wound up in the landfill.

Works great and easy to use
Color: Black
I feel like I’ve finally found a decent milk frother! I’ve gone through (or returned) several models over the last few years, but this one has a different design and hasn’t frustrated me like the others. It has plenty of power to froth milk, foam quality is good, heating is good. I checked the temperature a few times, since a few reviews were critical of that, and it was within a degree or two of what I’d set, so I’d say it’s good! I appreciate that it remembers the last settings so most days are a 1-click operation. But even changing the settings is easy - easier than others I’ve used while having more options.
