Solid Upgrade, Needs Color Variety
Replaced my old frother with this one and it's a solid step up. Seriously, better build quality, more features, and noticeably more control.
The variable speed dial is genuinely useful. Being able to dial from low (protein powder, matcha) to high (thick cappuccino foam) feels like an actual upgrade. The three whisk attachments give you flexibility depending on what you're making, and the included stand is a nice touch. Helps keeps the coffee bar counter from getting cluttered. Battery life seems strong so far; one charge has lasted through multiple weeks of daily use without issue.
Pros:
- Variable speed dial works well across a real range (not just "low" and "high")
- Three whisk heads included — good for different drink types
- Stand included; compact and stays put on the counter
Cons:
- Singular color option. The mint green clashes with everything on my coffee bar setup; wish there were neutral alternatives. ANY alternatives!
- Everyone may not like the price tag but it wasn't out of my budget and the included extra bits made it worth it for me.
If your kitchen palette doesn't fight the mint green, this is a capable, well-built frother at a decent price.

Mixes matcha well
This is great for mixing matcha due to being able to adjust the speed and make it slower or faster. The stand is a great bonus.

Rechargeable hand mixed.
Blends very well and fast. Sound is very quiet. Worth the price. Recommend to friends and family. Recharges fast. Very versitatable i.e eggs, frothing and drink mixes. Good power.

One of the best genral-purpose frothers out there, period
For the longest time, I've been looking for what seems like a unicorn -- something about the size of a mini-frother, but stronger than most. Almost a mini-submersion blender, really. And I still haven't found it. But the Maestri House frothers are about the closest thing I have found, which gives me hope that my unicorn might really exist someday.
Unlike cheaper frothers that almost always warn you off from actually washing them, Maestri House makes theirs waterproof. Seriously, you can froth sloppy and get it all up in the whisk end of this, then rinse the whole thing under the faucet if you want to. I really don't recommend that for the speed ring at the top of this one, as a precaution and because it should never be necessary, but you can if you have to.
Despite what I believe is cheaping out on the battery at just 1200mAh, it really can last a while, especially if you use it just once or twice a day. That it recharges using a USB-C connector is definitely a bonus.
The speed ring at the top is great feature, overall. It turns on at a slow speed and lets you crank it all the way up to a speed that I still haven't found a good use for. This provides a lot of flexibility, from gentle mixing to full-on danger frothing.
The included whisks can all be pretty handy. The whisk-whisk is good for things like two or three whole eggs, and the frother-whisk is good for general-purpose frothing. I really haven't figured out what the hook-whisk is for, because this isn't really made for handling any kind of dough, but it might work well for medium-to-thin batters.
Generally speaking, I can easily recommend Maestri House frothers over just about any other handheld frother you're going to find. For completeness, though, there are a few things that I think could be improved upon:
- The battery. Once you're into the $25+ range, I would expect a a high-current 2000mAh battery, for longevity and torque.
- The speed ring is flexible, but depending on your dexterity and grip it can be tricky to operate when dialing in just the right speed, with just one hand. And there's no "Off" button, so you have to wind it down to "Off". For some reason I often end up spinning it the other way and making it go faster instead. Muscle memory should take over eventually, but still. A dedicated On/Off button would be handy.
- For as beefy as this device feels, it doesn't handle thick liquids as well as I expected. The torque for basic mixing and frothing tasks is more than enough, but get this into thicker liquids or even four+ eggs, and it starts to bog down.
- Like most frothers of this type, the balance of the whisks is a variable thing. If a whisk shaft gets even a little bent this thing will shake, at least when started at slow speed. Things usually settle out at higher speeds, but I'd really like to see the shaft of the whisks made thicker and more rigid so they don't bend so easily.
- The frother whisk is good for what it is, and will quickly make great, basic foam. But unless you have supreme technique, it probably won't be good for any kind of latte art. This isn't a big problem in my mind, just something to be aware of.
- The stand is okay at best, and unstable at worst. It's just a bit short for some whisks, so some of them can bottom out on the counter and make it unstable. Bending the holder at the top back just a bit with some good pliers, so the whisks are tilted up and away from the bottom, can help. I'll probably end up designing a 3D printed stand to hold this more security, as well as store the extra whisks.
- I'm really not a fan of the textured finish on this model. It feels good enough, and the color is okay, but there are obvious seams on each side that, in my opinion, take away from the aesthetic. My call would be that whatever finish might be on the body, it should be seamless around the entire cylinder.
I want to be clear, that none of the comments above are intended to warn you off of this if you're looking for a very good, well made frother. I doubt that you can find anything better! I only mention them because nothing is perfect, and to temper the reader's expectations.
This brand, if not this specific model of frother, is almost certainly everything that you are looking for. If there's anything you don't like about this particular model on paper, I urge you to consider literally any other handheld frother they make.
It only falls short compared to my unicorn device, something I don't ever expect to see from anyone else, but really believe that Maestri House could deliver if they think there's a market.
