Subminimal NanoFoamer Lithium Performance Milk Foamer | USB-C Rechargeable, IP4 Waterproof, Dual-Speed, Stainless Steel | Premium Microfoamed Milk in 30 Seconds, Barista-Style Coffee Drinks at Home

I previously owned the version that required 2 AA batteries until the end rolled off my coffee bar and it shattered. I wasn’t a fan of how quickly that mode went through batteries so this time around I bought the upgraded lithium battery version. I am very impressed with this version and I wish I would have bought this model the first time. It’s a lot more powerful and it leaves the milk froth with a smooth and silky texture.

I love this thing, just used it with my OutIn Nano to make a delicious cappuccino in my hotel room. As a bit of a coffee addict, traveling sucks sometimes. Sure I can get a cappuccino at a coffee shop, but not before I wake up, get showered, get dressed, and drag my tired self out the door. With this frother, my OutIn Nano, some shelf stable milk, a few Nespresso pods, and a cup I can whip up a tasty cappuccino or latte before I try to get my day started. So let’s talk about how it works. It’s a handheld frother. You put some milk in a cup and turn this thing on and it froths the milk. But holy sweet mother of whatever savior you believe in, this thing is POWERFUL! I wasn’t expecting it and made a little bit of a mess the first time, but now I know better and the second time was perfection! This doesn’t heat the milk, so if you want hot milk you’ll have to be staying somewhere with a microwave, but for me the OutIn Nano makes the espresso hot enough that it works out. The two screens let you choose your foam texture, which is nice, the finer one is more like a micro foam, while the coarser one is closer to what you’ll get with a more traditional, whisky type frother. The travel cover is a brilliant addition, keeping the extra screen within easy reach and protecting the whole setup. I didn’t worry once about things getting damaged in my backpack. Definitely worth the $50 price tag, and makes me seriously consider getting their carafe-based model for at home, even though I’m really happy with my Instant Pot brand frother. Subliminal makes a quality product for sure!

If you love a high quality and sleek design frothed then this is perfect for you. Not only does it have 2 different speed settings it also comes with 2 different nano screeds so that you can customize the amount of foam. Also very easy to clean and comes with a wall mount. It works perfectly with my non-diary milk which usually takes so long to froth but with the NanoFoamer this is quick and gets the job done.

This is a well designed product, but made with plastic components of very poor quality. It does make good foam, as advertised. It is indeed better compared to other hand held milk frothers that cost less than a fourth of its price. However, the impeller broke within two months of usage! I have been using it 2 - 3 times a day. In other words, I used it for about 100 times before it broke! See the attachments! Now I have to get a replacement impeller if I want to continue using it. They do have a replacement part for $7 + shipping at their site! Amazon shows a cost of over $25 for the impeller alone! It must be a good business model!!

I ordered this product in January 2023 after my Zulay wire foamer stopped working after less than a year. While waiting for it to arrive, however, I found a tiny screwdriver and took my Zulay apart, and found that the problem was that over time milk had gotten into where the wire rod enters the motor housing, and solidified there, and that was what was stopping the Zulay from working. The other problem with the wire foamers, however, is if the wire rod gets bent even just a little, it dramatically reduces effective power. But with a little cleanup and careful straightening of the rod, I got the Zulay working like new again, just as the Subminimal arrived. Unlike the Zulay or similar, the Subminimal has a thick rod that cannot be easily bent. Also, the propeller and screen of the Subminimal is super easy to keep clean, which is not true of the wire foamers. I like my milk hot, so a certain amount of scalded milk builds up on the coiled wire of the wire foamer (true of all brands, not just Zulay). This doesn't rinse off, so requires occasional soaks and careful scrubbing with a soft toothbrush. To clean the Subminimal I just stick the business end under hot running water and turn it on, then remove the screen and repeat the rinse, then put the screen on and store. For the latte artist, the Subminimal is going to be the preferred tool, and they provide website tutorials on how to get the perfect foam and make those fancy designs. Honestly, I'm about convenience and tasty lattes in the morning. I pour my cold milk into a tall ceramic mug, and heat it in the microwave while I'm making the expresso in an Aeropress. I whisk the milk in the mug and pour the expresso into it, which is opposite from what a barista does. The Zulay wire foamer is FAST. It creates a dense foam of mixed bubble sizes (not ideal for latte art) in about ten seconds. In fact the Zulay is so powerful that it is pretty hard to use in a shallow round cup without making a mess, but it works great in a tall mug. With the Subminimal I get a dense microfoam on top of liquid milk, with less volume overall in the mug. Pros and cons for both. I really hate "disposable" gadgets, so I love the durable quality of the Subminimal. But for early morning ease of use, the Zulay wins. For the absolute best quality foam throughout my mug, I had to use both! The Zulay very quickly created a high volume of mixed bubble size foam, and then the Subminimal churned it creating a high volume microfoam. However... 3 months later the Zulay crapped out again. After a year of daily use, however, the Subminimal is working perfectly. The plastic housing of the screen did break after about 9 months, but replacement screens are pretty cheap on the Subminimal site. The Subminimal isn't as good as a barista's hot steam foamed milk, but it does the trick, is reliable, and quick, and is built to last.

Drinking an espresso or a matcha is something I enjoy without adding any adjuncts. However, I sometimes buy coffee beans or Japanese matcha that's highly regarded, but I find them as being just okay. Rather than just put up with them until they run out (which tends to lead me to ignore them for coffee or matcha I actually prefer), I am learning the advantages of lattes. Barista grade milk substitutes froth up beautifully. If I cared about latte art, the results are certainly very good. Frothing the milk substitute (high speed), then blending in the matcha (low speed) works perfectly. Powdered cocoa and spices are incorporated perfectly, too. The propellor and screen combo is far superior to the round spring most frothing tools have. Clean-up is also ridiculously easy; no dishwasher required. It will likely be a traveling companion on some trips as well.

I like the build quality, it feels nice in your hand. The instructions were easy and quick to understand~ we were able to pour & foam some milk in just a few minutes because this thing is powerful. The end product was light & airy, tasted great with our specialty coffee! This foamer also came charged out the box, which is nice, and it comes with a second type of filter head. Not only does it have an internal rechargeable battery, so you don't need to power it with disposable batteries, it is also quite powerful~ it's got a fast motor despite running on its own battery, so you can take it anywhere and still have great milk foam for your drinks 🙂

Product is excellent! I bought it because I don’t like my cups getting scraped with the stainless milk frothers. I am not creating fancy lattes but rather mix protein powders in my coffee. Mixes them perfectly! I’ll bet it would make beautiful foam designs too. Very powerful. Haven’t had it long enough to opine on battery issues discussed in other reviews. Hopefully the company gets that figured out before I have to replace.
