Works great!
Color: Black
This rechargeable milk frother works really well. I love that it comes with three detachable stainless steel whisks — it makes it easy to switch between frothing milk, mixing drinks, or lightly whisking other ingredients. The three speed settings are great depending on what you’re making, and it has plenty of power without being too noisy. The rechargeable feature is a big plus since I don’t have to keep replacing batteries and it works for many mixes before having to charge it. It’s comfortable to hold, easy to clean, and works quickly. Overall, it’s a great little kitchen tool and feels well made. I did unfortunately put the handle in my sink and it got too wet (not submerged) and did not work and I had to order another one. So be careful not to get the handle too wet.

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.
