Putting my $.02 into the mix
Size: Basic Frother, Color: Black
My old, lame hand mixer finally gave up the ghost. I ordered one of those “stick blenders” but it was waaaay too powerful for my purposes. (I don’t need it to dice/chop/pulverize fruits or veggies - if you need that, this mixer isn’t for you.) I needed something in between. I kept coming back to the “milk frothers,” but I had my doubts that one of those could mix up my morning shake. I tried a frother some years ago, and it wasn’t designed for blending ingredients, just for frothing liquids. Still, I had an idea (like some of you might) that what I needed was not a true stick mixer, nor a true milk frother. Something in between. I needed a “frother on steroids.”
I settled on this one-the YUSWKO YW-218. It had the regular frothing head, but also two other heads. One looks like a mini bread hook; the other like a mini whisk.
I plugged it into charge and it did take the stated time to come to a full charge. (Like any kid with a new toy, I tried turning it on before charging, but the low state of charge resulted in the high-medium-low settings not behaving correctly.)
For my first few forays into blending, I tried the mini bread hook thingee. It worked OK, but not as well nor as quickly as I wanted. I then shifted to the mini whisk thingee. I didn’t really prepare well. I combined my milk-protein powder-carnation breakfast-malt flavoring-imitation (yeah, I know, it probably causes cancer, but only in California) vanilla flavoring concoction into my normal medium-sized concession cup (you know, the smaller ones you get at high school basketball games), lowered the whisk head into the goop, and turned it to “low.” In a second, I was wearing my shake. But the power capacity was more than enough to do what I was needing.
Anyway, since that first attempt with the whisk head, I’ve gotten the routine down. And it is EXACTLY what I needed. (I’ll try to attach a video to show you.). Clean up is simple. You can do it with soapy water and a brush or rag, but I just run the thing in clear water and ensure I get all the sticky stuff off. I tried the soapy water, but I got a LOT of suds.
A few pointers. First, charge it up all the way before using it. I haven’t had to recharge for two weeks now. You’ll use a regular, small phone-charging brick. (Two words of CAUTION. I found that the included, cheap charging cord did not work. It got really hot, like there was an electrical short in it. So I found one of my own. Also, DO NOT USE the larger charging blocks like the ones from Ap*le. I tried and it was too much.) Second, I assumed that the low speed would be the less aggressive and thus the less “throw-stuff-out-of-the-cup” setting. But that hasn’t proven true for me. I’ve found that the medium setting makes my ingredients behave better (less throw-out and quicker blending). Experiment with different speeds, even though it may not make immediate sense. Third, practice with plain water first (I’ve already told you how I know this). That’ll give you a “feel” for what this frother will do. Fourth, practice with different sized cups. I’ve since changed to the taller concession cups, as they prevent throw-out. Fifth, start practicing with your cups down in a sink. Less mess to clean up and no need to change clothes before you head out to work or school (I’m a teacher). Finally, familiarize yourself with the way the three buttons work. My previous mixer required me to keep the button depressed to blend. If I let up on the button, the unit would stop. Not so with this one. A light press to start, let go, then a light press to stop. Don’t keep mashing the button.
Final thoughts: this frother is just what I needed. If your experience sounds like mine, I think this one’ll give you good service.

Perfect and convenient tool
Size: Basic Frother, Color: Black
I am very happy with my new milk frother. Really easy to use and I was very pleased with the results. I got to enjoy my first home made cappuccino and it was perfect. I have only used the frother attachment so far but I plan to use the whip the next time I scramble a couple of eggs. Very please with my purchase.

Powerful, Fast, and USB-C Rechargeable – Way Better Than AeroLatte
Size: Basic Frother, Color: Black
I’ve been using this daily for several weeks and it’s been excellent.
I use it to mix creatine, whey protein with milk, and to froth warm milk. It handles all of it without issue.
Strong motor. Mixes powders fast with no clumps
Great for frothing. Milk comes out smooth and consistent
USB-C charging is a big upgrade. No batteries to deal with
Holds a charge well even with daily use
This easily outperforms my old AeroLatte. It’s noticeably more powerful and gets the job done faster.
If you mix supplements or like frothed milk, this is a solid buy.
