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.
