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.

Best addition to our coffee bar
Color: Black
BEST milk frother we've owned. It is on the larger size but worth it. I love that there are multiple temperature settings. It is easy to use and figure out. The frother spins inside of the stainless steel cup and is magnetically attached inside so it does not come off easily. We use agave for sweetener and being able to throw the cup into the dishwasher to clean off residue has been the biggest plus of this frother. Highly recommend. Worth the cost.

Cute, functional, works great!
I LOVE this thing!! It froths the half and half for my coffee and cream for my tea so beautifully. It's fast, and easy to use and clean. Really adds to my morning routine to be able to choose a temperature and froth level to my coffee creamer. The color is so pretty and both it and the style fit right in with my kitchen decor. I've been using it for several months and haven't had any issues to far. Great item! I was afraid it would just be more clutter and gadgets I didn't need taking up counter space, but it fits right in next to my coffee maker, and I truly do use it every morning. It makes my coffee even more enjoyable, believe it or not. Love it!!

Solid purchase
Color: White, Color: White
I have used it often, basically daily. I love how it has a magnet stirrer and therefore is quiet. I like the stainless steel aspect. It does heat up well. It can store two regular mugs of beverage or maybe 3-4 mugs of froth. It is lightweight but doesn’t feel cheaply made- good enough quality. The froth is great- I have no complaints. I had to learn the hard way that non-homogenized milk gets grainy- weird and icky. I wish it was a little more frothy on the matcha side of things but I still use it. Also, I wish for things like hot chocolate that it got hotter. It goes to 160 on the machine but it doesn’t feel that hot when you drink it. I haven’t measured the temperature of the drink yet but it isn’t hot hot.
