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.

It delivered on more levels than I imagined or expected
Color: White
EDIT: I've used this frother pretty much daily, sometimes more than daily, since ordering it, and it has performed very well.
I make turmeric/ginger/pepper milk most nights. The way this frother performs for that use astounded me. I bought it for coffee/cocoa/mushroom drinks, then while waiting for it to arrive realized it might work with the "golden milk."
First, the little frother uses a closely/precisely applied heat drawing 550w. The thick steel pot nestles down into the heating base, and the cover fits nice and snugly. So I'm not heating an entire thick saucepan perched atop an entire stove burner (1,000-1,500 w), with all the escaped heat that involves.
Second, I'm not standing there with thermometer in hand, diving into the open pan of heating milk to find that perfect sweet spot around 150-155...while constantly stirring and making sure not to let it boil over.
Because, third, the little frother takes care of that part, with the thermostat auto shut off.
Fourth, it whisks the powders smoothly in. Manufacturer suggests starting the whisk movement in the milk, then adding the powders. They did collect a bit in the low vortex around the stem of the little assembly that holds the various whisk/stir/froth blades, but I just stuck a spoon handle in there carefully, and it redistributed easily around the magnetic-driven stirring assembly.
And finally, omigosh, the lovely velvety texture!
Since these spices express best with extended warming, I'm making one batch, heated and frothed to 160F, then follow that with just milk frothed to 140. While the second batch is running (there's a cool down pause in the process, hastened by rinsing the pot exterior in cold water and of course drying it before putting it on the base), the first batch is steeping the spices...so the combined result is perfect.
EDIT: It did its job much faster than I expected (minutes). So I tested it as promised on my "solar generator" backup unit. My thought was that this would make my usual most efficient option for heating milk in those conditions the second most efficient: open saucepan atop a multi-watt-level portable induction cookplace on the 600w setting. And with much less cleanup at a time when water is scarce (electric well pump). We had a power outage here last week. Yep, the 550w frother ran on a Jackery 2000 for the few minutes it took to heat/froth milk--no trouble whatever and hardly put a dent in the charge. WOW. (Technically speaking it could run continuously, continuously heating, for over 3 1/2 hours on a full 2000 kWh charge.)
EDIT: This isn't a reduction in stars, just an observation. The frother "tree" assembly that does the business of stirring/whisking/frothing--I thought to order a spare in the event of damage to the original. They are very hard to find online. Maestri House lists the replacement part as "out of stock." Also out of stock, replacement pot and lid. This might be a concern to some considering the tool. But it seems to be well made and I hope gives long service.
EDIT: As of May 2026 the little frother is still working exceptionally well on a nearly daily basis. I purchased it in October of 2025, so that shouldn't be a surprise...but just sayin'. :^>
