Great look and very powerful - consider what your wanting to froth/mix - may be too powerful
Color: Lux White, Size: Rechargeable Z1 Motor Max
It's a great frother - but more for large drinks. Very powerful, even on the low speed. I returned it because I want something to mix my collagen and creamer in my coffee. The first time I turned it on it shot half the coffee out of the cup - very powerful. It has a great look, sleek and fits easy in the hand - but for what I needed, two powerful. It would have been nice to have a fully adjustable speed wand like my replaceable battery powered frother.

Powerful, rechargeable battery, easy to use & clean
Color: Lux Absolute Silver, Size: Rechargeable Z1 Motor Max
2 speeds, easy to change back and forth to different speeds with one click , easily blends 1/4 cup protein powder in 12 oz milk on low speed. Easy to clean: Stick blending wand in tall glass with warm water + dish soap, turn on low speed to clean easily (don’t stick the part that holds the battery in glass). Also of note, chosen by Americas Test Kitchen as best milk frother but I use it to make protein shakes.

Works great on bullet coffee!!
Color: Lux Alpha Black, Size: Rechargeable Z1 Motor Max
I am really pleased with this frother! Frothers I have used in the past didn’t mix my decaf coffee, 2% milk, and MCT oil as thoroughly as I like (oil and coffee separated). This frother blends everything AND I get a nice layer of frothy milk on top!!! Charge lasts a long and the froth can be submerged all the way up to the button!!!

Compact, lightweight, and useful milk frother.
I ordered the Electric Handheld Milk Frother in the Starlight Black color. I don’t drink coffee, let alone fancy coffees where I would normally need a milk frother, so I bought this for one reason and one reason only: scrambled eggs. I make a ton of scrambled eggs.
Now, I can whisk eggs by hand just as well as the next person, and I’m not entirely convinced a frother whips them better than I can, but regular whisks take up a ton of room in my drawers and this does not. I really just wanted something compact that could whip my eggs into a nice frothy consistency without taking up much space. Even better, this one looks nice enough to just leave sitting on the counter where I can grab it easily. I will note that although I can hand whisk easily enough, there are many people who cannot due to arthritis or other issues, and this whisk is a brilliant tool for them.
If you actually want to use a frother for other things, this one does perform very well. It has three speeds and comes with three different attachments: a spring whisk for latte and cappuccino foam, a balloon whisk for eggs and cream, and a hook whisk for blending protein powders or mixes without lumps. I actually ended up using the hook whisk while making pot roast. I mixed the seasoning packet with water using this frother and it blended everything perfectly with no lumps at all.
The frother itself is lightweight, pretty quiet, and very easy to clean. The attachments detach easily and just need a quick rinse under soapy water. It also comes with a magnetic wireless charging dock that uses the included USB-C cable. The docking connection is simple and secure, and charging has been completely hassle-free so far.
The LED display shows battery levels at 25%, 50%, 75%, and 100%, which is useful for knowing when it needs to be charged. Overall, it’s a simple, convenient kitchen gadget that does exactly what I wanted it to do and I am quite satisfied with it.

Works great and easy to use
Kitchen gadgets have a way of accumulating. You buy them with good intentions, use them twice, and then they live in a drawer forever. This milk frother is not that. It's one of those rare small appliances that earns its spot on the counter every single morning.
The wireless charging is the feature that sets this apart from every other handheld frother on the market. No fumbling with a charging cable, no little dock that takes up extra space — just set it down and it charges. It sounds like a small thing until you've used it, and then it feels like the obvious way every handheld kitchen tool should work. The fact that it charges quickly means you're never waiting around or reaching for it only to find it dead.
Three speed settings give you real control over the result. Low for gentle mixing, high for a proper thick foam that holds up in a latte or cappuccino the way it should. The stainless steel whisk feels durable and substantial, not like something that's going to bend or corrode after a few months of daily use. The whole thing is well-made in a way you notice immediately, solid, balanced, and built to last.
The Starlight Black finish looks sharp, too. It's sleek enough to leave out without cluttering your kitchen aesthetic, which matters when you're using something every day.
If you make lattes or cappuccinos at home and you're still shaking a jar of milk or settling for flat foam, this is the upgrade you didn't know you needed. Easy to use, quick to charge, and genuinely well crafted.
