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!!!

Perfect for Lattes

Good for steaming 8-10 oz of milk. The nifty tool is good for scooping out your puck.
