perfect for mixing a couple of eggs
Color: Black
we don't use this for drinks, but to mix eggs. this is perfect for mixing 1 to 3 eggs very quickly and thoroughly. struggles with four eggs five eggs forget it. I know it's not designed for this. but it works perfectly and takes up a fraction of the storage space of a hand mixer. we leave it on the counter next to the stove in a large round bottomed coffee cup.

10/10 frother - no regrets
Color: Black
In full transparency, I've only used this with milk or while making dalgona coffee, which is what I bought it for, so I've only used the frother attachment so far. But it works fantastically. It comes with a little base it stands up on so it doesn't take much counterspace while charging, OR you can just plug the USB-C cable in directly and let it lay down. I think you do have to provide the adapter, but if you're like me you have several of them lying around anyway ;) It has 3 speeds, and can get really fast, so make sure whatever you're frothing in has high sides. My old frother was way too weak, but this one is absolutely perfect. It works great, it's fully rechargeable, you really just have to rinse it off to clean it, and it's more than worth the price.

Powwer, Speed, interchangeable Attachments, but a little too much Speed.
Color: Black
Why not 5 Stars? Something a little silly, but this frother is a little over powered. Not necessarily a bad thing, but for me, I need a slower setting.
Now the good stuff. I purchased a different, really cheapo frother to see if it was useful before I bought a better quality one (more $$). The cheapo one worked fine, mixing drinks, scrambling eggs, frothing milk. However, it was low powered, and thicker items like eggs caused it to burn out. This household agreed a frother was a useful tool and I picked this one. What is 5 stars about it? Three attachments- a spring type frother, a beater, and what looks like a thin dough hook. Interchangeability. Love it. Also, three speeds. Nice to have a choice. Operation? works perfectly. I Like rechargeability. So where is the missing star? It is stuck to the wall with the hot chocolate that sprayed all over. This thing is powerful for what it is. I wanted power. But the power comes at too high a speed. Low speed should be the highest, and 2 more slower speeds would be perfect. So we mix in a larger container to keep the contents in the container and off the wall.
TLDR: Good: Interchangable whisk, rechargeable, 3 speeds, lots of power. Bad: Low speed is not low enough.
If all you are doing is frothing milk in a deep container, this works great. Has the power to scramble eggs, for example. Mixing hot cocoa mix in a nearly filled cup will bring excitement though.

I love it, it works great.
Color: Black
I received the Electric Milk Frother, EW-071, about 2 weeks age and absolutely love it. I don’t froth milk or drink coffee either. What I do, do is for years I have mixed my own mushroom drink, way before all this mushroom coffee fad began. I also mix in other ingredients, collagen, creatine, ginger powder, cinnamon, and a few other items and the coffee frothers do such a poor job of mixing them all up. The EW-071 with the Balloon Wisk does a wonderful job. It is high powered so be careful, if you totally fill the cup expect a mess, think before using this unit it is powerful. I also like the on – off buttons. With the other frothers you have to hold the button, I hate that. I do keep my thumb close to the on - off button but have not had a spill yet.
Good job. Thumbs up.
Robert, Las Vegas.
