Very good milk frother for hot milk foam. I haven't tried making cold foam.
The only negative thing is that it is a bit heavy and it doesn't always make the milk foam velvety smooth.
It has a lot of marks from the type and fat of the milk chosen!!

I couldn't believe that I could have such a frother with just regular milk. Very good. I am satisfied. It makes both hot and cold froth and produces a sufficient quantity. Sturdy construction and easy operation. It also has a function for heating milk. Perfect. Be careful when cleaning not to wet the buttons. A little water and a cloth and it's okay. Plus, it is quiet.
P.S. After a year of use, I can say that it continues to work normally. The only issue is that it slightly sticks milk to the bottom when making hot froth.
