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! Read more

I've had this for the better part of a year and it's an excellent way to level up our home espresso game. The battery life is great - if used daily, I only end up charging it maybe once a month. The top speed is extremely fast, so I usually start there to incorporate air then submerge the blade and switch to 2nd gear so it can mix in the air and create good bubbles. I'm pleased with the microfoam this can make for the price point! It's SIGNIFICANTLY better than the cheapo foamers, and probably about 80% as good as what you can get from a steam wand (if the barista knows what they're doing!). Definitely recommend this for "pro-sumer" coffee nerds looking to level up without spending hundreds on an automatic espresso machine. Read more

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. Read more

UPDATE: I still cannot find a lithium battery that works other than one that has consistently bad reviews on Amazon. I have tried reputable battery companies. I contacted Subminimal, and they will do nothing because I am 2 months outside the warranty. However, I think anyone who purchases this is purchasing it with the expectation that they will be able to replace the lithium battery when it dies. I do not recommend this product. Decreasing from 2 stars to 1 star. ------- it works well but be aware the lithium battery life is only about a year, and it is not easy finding a replacement with the correct specifications. Why they would choose a battery that is hard to find, I do not understand. In addition, the company's video on how to replace the battery only provided partial specifications since it simply said to refer to the parameters in the battery housing on the device. After spending $15 on the battery + shipping, I realized it wouldn't fit into the frother. I'm going to add the specs here for anyone who already owns this milk frother. Good luck. Lithium button top 18500, 3.7V, 1400mAh. I'm throwing this in the trash and will be a foamer that is cheaper and without this lithium battery problem. Read more
