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!!!

Almost blew up my microwave

Size: 20 Ounces, Size: 20 Ounces

TL;DR "A hilarious microwave mistake turned into a great home cafe upgrade. This 20oz cup is straightforward to handle, looks incredibly professional, and holds a level of heat that will literally burn you if you aren't careful." . Bought this for homemade coffee brewing, just to spice things up. But as I go ahead to heat up my new shiny stainless steel milk frother cup in the microwave, whoopdy doo. Ya can’t put stainless in the microwave! Regardless, it’s still a straightforward frother cup to handle, making it a great dollar investment for upgrading my home cafe setup. . 1. Spotless Stainless Steel: Its sleek appearance made me feel professional in the hands of an amateur like moi. Great quality! 2. Temperature Retention: I accidentally burnt myself because it stayed so hot, but that is a major positive. Proving the insulation works perfectly and keeps the milk piping hot. 3. Size: The 20oz capacity is accurate, providing the perfect amount of space for frothing without any overflow.
