Handheld Mixer/Frother Review
A Premium Choice That Transforms Morning Coffee
I am thoroughly impressed with this handheld mixer and frother. Each morning, I blend cacao and collagen powder into my coffee, and in the past, I always ended up with stubborn lumps using only a spoon or whisk. I had previously purchased a few inexpensive handheld mixers, but they disappointed me both in price and performance, struggling to mix the powders thoroughly—especially at the bottom of the cup. I came close to abandoning handheld mixers altogether, but decided to give it one last try.
After reading countless reviews and carefully comparing models, I opted to invest in a higher-end handheld mixer. The anticipation was high—would this mixer truly distinguish itself from the budget options cluttering my kitchen drawer? From the moment I unboxed it, the difference was clear. The mixer felt substantial in my hand, and the build quality reflected thoughtful engineering.
While this model cost roughly twice as much as the cheaper alternatives, it proved to be well worth the investment. Initially, I was concerned about the dial at the top, fearing it might be difficult to control. However, I was pleasantly surprised by its intuitive operation. The unit offers a solid feel, plenty of power, and a versatile range of speeds—from a gentle stir perfect for coffee to an impressively fast setting.
I had not previously considered using this mixer as a frother, but as a cappuccino enthusiast, I decided to give it a try. I heated both 2% milk and oat milk to take the chill off, then submerged the mixing wand. Allowing the mixer to rise above the milk introduced air and created a rich, creamy foam—an unbelievable result. My homemade cappuccino now tastes like something from a café.
The controls are robust, the construction is reliable, and the power is consistent. Cleanup is effortless, requiring only a quick rinse under the tap. The battery life is also noteworthy, lasting through several uses without losing strength.
If you are hesitant to spend a bit more on a quality handheld mixer, I wholeheartedly recommend making the investment. This mixer has become an essential part of my morning routine. Excellent product—well done!

Very nearly the perfect frother for all your basic frothing & mixing needs
Color: Black
There are a lot of middle-of-the-road frothers out there. I've been through a few of them in my recent search for something that could mix and froth well, without taking up any more outlets in my basement kitchen. Of the three Maestri frothers I've tried so far, this one wins the race by a nose.
Most recently, these Maestri frothers come in basically three versions: A single-speed @ 8000 RPM, a two-speed @8000/5500 RPM, and this stepless variable-speed version. Aside from that, the only real difference in recent version pack-outs is which attachments they come with.
Look over the reviews of the single-speed version and you'll find that while it can and does froth well, it starts at a single, high speed and gets there fast. This makes it pretty easy to spin liquid right out of most common cups and mugs.
There is a two-speed version, but it's harder to find, only comes in one color (Grape Purple), and while it's much better than the Maestri single-speed, it still has a couple of quirks that make this variable-speed version win out.
This mixes and froths whole milk, half-and-half, or heavy whipping cream, or just about anything else very well. Like all frothers, it takes a little time to learn its nuances and nail down the technique, this will definitely get you there.
The best feature of this is easily the speed control. Turn the knob to turn it on at a low speed that's great to get things started, then turn the knob to crank up the speed just enough to do what you need, whether that's mixing or frothing. The low starting speed makes it easy to keep things under control without undue spilling, and the max speed is more than enough to make quick work of getting your froth on.
There are really only two complaints I have with this stepless, variable speed version:
- I'd really like to have a Press On / Release Off button in addition to the Speed Control knob. More than one time have I gone to turn this off, only to spin the knob the wrong way and crank the speed up to ludicrous, sloshing liquid on the counter. Being able to turn it Off just by letting go of the button would be quick and easy. This configuration would allow using a preferred speed right from the start, while still allowing speed to be adjusted on-the-fly when needed.
- Give it a bigger battery. It would cost mere pennies to give this a 2000mAH+ instead of a 1200mAH battery, and I can't think of any reasonable downside to that.
- Give the motor a little more torque. It's fairly easy for the current motor, at any speed, to get bogged down in a thick protein powder mix, or when pressing the frother or other attachment a bit too hard into the bottom or side of the frothing container. A bit more "oomph" would prevent that.
I really like the overall design and features of thes Maestri frothers better than many other, cheaper versions. This variable-speed version is pretty great as it is and probably the one I would recommend over the single- or two-speed, for most people. But I often find myself using two hands -- one to hold it steady, and the other to turn it on and tweak the knob to the desired speed(s) -- for a device that should arguably need only one hand to use. Just a couple of minor tweaks as noted above would make this the overall best frother of its type that I've used.

Hands down, the BEST handheld frother I've ever used!
Color: Black
Hands down, the BEST handheld frother I've ever used! I got the black one, but any color will have the same results.
Over the past 12 years or so, I've used so many different handheld frothers and they've ALL fallen short of expectations for quality, longevity, power, features, and usability.
I've used everything from cheap, $15 models to $50+ models and everything in-between. Some with fancy attachments for various types of mixing, frothing, beating, whipping, etc. Some with rechargeable batteries, some without. Some AC powered, some with fixed whisks, some with detachable/replaceable whisks, some with stands, etc. NONE have been spectacular. Most broke within 6 months and got tossed. ALL were major disappointments in the end, including the "revered" Zulay models of which I tried several.
I finally found this Maestri House branded, variable speed frother with detachable / replaceable whisks and got one to try. I was literally on Cloud Nine the first time I turned it on. Like, WOW! Not only was it FAST on the highest speed, but it was powerful enough to churn right through milk, eggs, cream, etc, without bogging down like many others.
This thing makes milk froth like a milkshake and Matcha Lattes like nothing else I've ever experienced. I used to have to sift my Matcha, then whisk it in hot water, then froth milk and then blend them together to make the perfect latte. and if the milk was cold (my preference), pre-whisking in hot water was a must to avoid lumps. However, with THIS frother? I literally pour my milk into a tall tumbler, drop in un-sifted Matcha powder, and spin up the Maestri House frother at first on a medium low speed to get it mixed, then jump straight to the highest speed to really whip that milk and match up. After about 30-45 seconds, I've got the thickest, richest, smoothest, most aerated latte around. And NO LUMPS at all!!! What a time and dish saver!
And cleaning? I just run it under hot running water to get the shaft cleaned and then spin it up in a dish with hot running water for a few moments, then spin it on high for a few seconds in the air to dry it off instantly.
Now, I'll be honest here, too. The specs say it can go months on a charge, using it for a couple minutes a couple times daily. Well, I guess it could do that and still spin. But I use it FULL SPEED, churning hard for at least a minute a couple times per day. After about 2 weeks, I can start to notice a speed reduction so I just plug it back in on the charger. All things considered, this is still better than all the other handheld frothers I've used over the years.
After using the heck out of this thing for the past 7 months, I've even decided to start selling these in our Japanese gift shop. The manufacturer is has been very responsive both in customer support (I called them about an issue I thought I was having, and they called me back with a couple hours even though I didn't leave voicemail when they didn't answer right away) and in reseller support. I have to give these guys an A+ for responsiveness and quick resolution when problems might arise.
HIGHLY recommended!!

Great Addition!
Color: Black
Why did you pick this product vs others?:
I just started a powdered drink routine recently and was having a difficult time mixing it with water. I would consistently end up with small nuggets of mix making it unenjoyable to drink. I knew I needed a mixer and was glad I found this device when I did. It works perfectly! I like the fact that it comes with its own stand and included two mixing heads. It is solid, well-designed, and you can feel the quality when you pick it up. The variable speed of the mixer is perfect for ensuring that everything is blended well. I haven’t used it to “froth” anything yet, at least not on purpose, but I accidentally found out that it can do that well. This is a great addition to our kitchen and is very easy to wash after use. So far…no issues. Highly recommend for those of you looking for the right tool to make sure those protein mixes aren’t full of unmixed nuggets.
