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 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!

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.

The foamer works very well. Quite handy!

Best performing handheld foamer I’ve used, but also the most fragile. If you drop it, even once, it will break. The shaft is made of metal, but it’s only a few millimeters thick. For some reason it’s attached to the motor with a very narrow shaft. This seems like poor engineering to me and caused it to break after 1 drop. They also don’t stand by their products. They offered a 15% discount from the nanofoamer on their website after I showed that it broke after less than 3 months of ownership from just 1 drop. That discount would make it MORE EXPENSIVE than if I buy it on Amazon today because I get free shipping from Amazon. Also, I paid $10 less for it when it was on sale. So they refuse to give me any discount whatsoever and it’s “unrepairable”. Don’t buy this unless you’re okay with spending $40-$50 +tax for a replacement every time you drop it. It was pretty good while it lasted, but it’s cheaper than it seems and poorly engineered. $5-$10 rechargeable frothers are significantly more durable

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.

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.

I have to preface this review by stating that I’ve never used any other hand frother or steam wand either I’m a complete novice Having said that, I saw a 20 second video on Amazon and that was it. It’s really not rocket science, but it does take a bit of practice to feel comfortable with it Just remember to use a larger pitcher than you may need, because you’re adding air to the warmed milk and it will increase volume I found this out on my first try and nearly had the milk swirl out of the top Outside of that, it frothed the milk easily and quickly. Less than 30 seconds You can get cheaper hand frothers, which is fine. No one needs to spend this much to froth milk. However, it is easy to use and it has a cap so that I can take it to work with me I believe the cheaper ones take just a bit longer. Maybe a bit more than 30 seconds. And according to a barista on YouTube, a little more work. However, very doable The Nano Foamer makes it easier due to the spinny bit on the end, which is a mesh screen while the others are a spring I managed some nicely frothed milk with microfoam and since it was my very first time, I also inadvertently ended up with a very airy whipped foam as well. But I think with a bit more use, I’ll be able to control the frothing more

Overall a well made product and does the job better than the others. Not just for coffee and milks, but can use for cocktail foams & other drinks Pro- - Sleek - Easy to hold and use, less risk of slipping with the flat sides. - Powerful foaming action, will make foam easily from cold and hot liquids. (that are meant to foam) - Its rechanagble, say that again with me rechargeable. Last weeks used every other day for 3 weeks before I had to charge using 30 sec a day- - Very portable to bring camping or to a weekend getaway. - Easy to clean Cons- - Unitasker Other- - Will not fully replace a milk steamer but will make your milk nicer when its messed up. - Not really going to make latte art foam with this easily. - The protective storage tube over a long time or heavy usage will wear down and become loose. ** Would highly recommend for any foam beverage lover. Makes a great relatively inexpensive gift.
