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'. :^>

This is the one to get
Color: Black
I find having separate controls for temperature and foam density is critical and this model nails it. The "newer model" listed in the product description eliminates the separate controls and does not function as well. This frother also has nice features such as the ability to produce cold foam and easy cleaning. It is also extremely quiet. I've tried several mid-range electric frothers and this is the best.

So far. so good.
Color: White
This is my 3rd frother that I purchased from Amazon. The others were brand name frothers that broken within a few months of use. I won't name here (hint: begins with an N and ends with an o) This Milk frother from Maestri however works excellent. Multiple heat and drink settings and makes the perfect foam every time. I especially like how the pitcher is removable from the electric base and can be washed with out worry. easy to use. Just read the manual to understand all the settings, makes a perfect froth in less than 2 minutes. I've only had this for a few weeks but I am impressed.

Loving it so far!
Color: White, Color: White
02 Nov 2025 I've only used this twice and I already love it. My main reason for buying it is for protein hot chocolate I drink twice a day. I previously made it at the stove and that took 13 minutes of constant mixing to reach 160°. My hot chocolate is 1 cup of milk, 1 tbsp each cacao powder and panela (sugar), 1-2 tbsp collagen powder, vanilla extract, and 1 whole egg. I premix everything before pouring it into the frother because, while it may be able to handle the powders, there's no way that whisk will be able to break the whole egg enough to thoroughly blend it before it starts cooking. I'm totally fine premixing the night before and heating it in the morning. I made the first batch this morning with 2 cups of milk doubling only the cacao and sugar which brought it to just below the top max line, and it came out perfect. It was smooth and there was no burnt taste. I used the recommended hot chocolate attachments, lowest froth setting, and 160° temp setting. I had almost no froth in my hot chocolate which was perfect. I removed the pitcher as soon as it was done to prevent any burning. I checked the temp with a thermometer and the temp was actually 165°. I don't really know if that would impact the taste if there was less milk. For the 2 cups, it was still perfect. I do wish there was a little more temp control like a 150° or 155° setting. I also wish it was able to give you the temp as it was heating in case you want to pull it off just before it hit the set temp. The bottom right button is superfluous. It helps with the foam setting, but you can also simply press each of those buttons directly. Cleaning is super easy, just remove the pitcher and attachments. I love that the attachments are magnetic, but I recommend taking them out before pouring because the magnets aren't that strong. All in all, great for the price and perfect for my needs.

Works great with soy milk
Amazing steamer with high volume capacity. I can make large lattes. I love that it let's you choose your temperature. I use soy milk, and it works perfectly every time. When using at max temp, only a tiny bit of soy milk gets a little burnt on the bottom, and it scrubs right off. Since the little whipping tool comes off on the inside, it cleans very easily. I love that the little whipping tool is magnetically attached, too. It's super easy to work with and very secure. My 8 year old uses this all on her own without issue, which proves how easy it is. Highly recommend.
